Trial ends and Green Speeds

The tournament is about to start and everyone is on the Green 10 to 15 minutes early for trial ends. "I guess this is a chance to see how close I can roll to the jack". This used to be my thought on trial ends. (In this photo is the greens fast or slow ?) Hint.. photo has been squeezed to help you see the speed of green)


Or I thought "one of the reasons for the trial ends is to show you how your Bowls performs on this clubs green". Today I think differently, although we all know that the club bowlers have an advantage on their greens.

When I was 21, now going on 70, I was working for the newspaper and studying photography. A mentor told me, " there are some professions where secrets are your bread and butter ". "In news photography there are many tricks to making a great photograph, and unless someone tells you their tricks, your photographs are like everyone else's photos" he said " become friends with the better photographers and learn the tricks". Trail Ends are bit like photography. Learn the tricks.
)
In our provinciall tournaments, Jeff, from out of town, can always be seen on the Green rolling Bowls in the opposite direction of play before the trial ends. If trial ends are just to know the speed of the green, and anyone can do these practice rolls before the game, then  what is the purpose of trial ends?

OK, imagine that you have three sets of bowls which roll differently and have a different biased. In this Blogs I will convince you that every green causes your Bowls to have a different bias. ( and every green will appear to have a different speed). If you have to choose one of the three sets of bowls for this competition, why not choose the Bowls which you are most comfortable with.
After having bowled your Bowls several hundred times you have a visual image of the line of delivery needed and you know the final finishing curve of your bowl's bias. However, consider this............ 
If the faster green changes your regular bowls' bias and by choosing another set, maybe yournset number two Bowls, you may find that they perform with what seems to be the same bias as your regular Bowls back on your home green. Certainly you will be bowling a better bowl if the competition green performs like your home club green. The bowl choice will do this for you.
.
I don't know if the rules allow you to change your Bowls following the trial ends but before the game starts you can roll all your bowls (two or three sets) in the opposite to competition direction. By doing these pre-trial ends rolls of your bowls, you can actually find the best bowl and when you come to the mat for the trail nds,  you have changed your Bowls  to the best performance.
 
You doubt this...?? ? In the clubhouse on the wooden floor roll your Bowls very slowly and you will discover, if the floor is flat, that it will make a complete circle of about 10 to 15 inches.  YES, they will return to the start. why?
Instructional books on lawn bowling will explain that the biased or curved of your Bowls only takes effect in a few seconds before stopping. Much like how a car tire will stay upright while rolling fast and begin to fall when rolling slow.  The photo above, has all the bowls standing (see the sticker on the side)  indicates a very slow green and your bowl stops very quickly.

However, if the greens are fast, this slow roll will last longer and because before stopping the bowl wants to fall over and  like on the fast hardwood floor ( or fast greens ) allows it to continue to roll there is an "extended bias"

  Don't just read these Blogs and think maybe, get out on the green or in the clubhouse and try what is suggested.

The faster the green, and the slower you must roll your Bowls, the longer the bowl will roll as it is finishing its delivery, at the "bias curve roll", and the more it will seem to turn into the jack. Your Bowls will seem to remain at the slower speed (bias curve ) longer. I had a set of bowls which seemed to turn around and come back before stopping, much like a candy cane. 
  Of course, the greens were prepared by Scott and were rather fast. Hint.. also, the faster the green, the more likely your Bowls will fall over rather than stand up straight. 
In teaching Lawn Bowls to a beginner this will not be discussed but to you the competition bowler this can be very important. 
Do you have a different delivery with very heavy and slow green.  Look at the British bowlers with their two steps after delivery. We often teach and think that the delivery should end with one step. But when we have a very slow green we may need more body movement forward and be required to do two finishing steps in order to stop your movement after the delivery.


The YouTube video "Lawn Bowls: Tony Alcock 16 Time World Champion Coaching " suggest this is the " Scottish runner " style of delivery because Scotland having slow green, required such force that it requires two steps
or more. Will these bowls have a big swing or Bias?? NO
because they will not spend a great deal of time during the last few seconds or it'sfinish and  will appeared to have stopped very quickly without having a finish or curve.  Like the photo above, you will probably notice the bowl is often in the standing (running) position after it has stopped.

There are many other factors which could affect your bias. 

The way that the greens are cut (cross, up/down or crisscross). These will change the delivery speed and therefore the bias. Of course, as we bowl and are going up the alley the green speeds will change from our walking.  Also you may discovery that one way maybe faster than coming back, as you roll with a cut of the green and against a cut of the green. You may also notice that during the morning with the dew it is quicker..

These will cause what seems like a change in speed and the finish of your Bowls.
If the three sections of the bowl's roll are the Straight (line) the Middle curve, and the finish, what are the effects of green speed and green cut height to the Straight and Middle curve of your bowl ?

Next blogs will discuss how your natural distances of delivery should be evaluated during trial ends.
