I completely agree with the making the game look effortless and smooth comment. No question about it, those bowlers seem to just fluidly slide through their shot. I personally have left my hand in that poised form from time to time to better note what happened and how it happened but I do prefer to let the arm do its natural discharge still. However, I don't think this makes the bowler any less impressive and considering how every bowler has a certain individuality to their form and their shot (If you analyzed every bowler and picked apart every tiny part of their style and approach I doubt you'd find too many that had the exact same look, if any at all. Somethings are better kept to the books, so to speak, but there will always be something that speaks to that bowler specifically and not all other bowlers will do) I find it amazing that with all the different styles and variations, each bowler can still create the same end result with different setups. I guess its kind of like pitchers in baseball, where there are plenty of different styles and forms with a certain standardized pattern that is outlined in each form, but then varied slightly to match the player individually. Think of all the crazy looking forms that pitchers have compared to one another and think of bowlers doing the same thing. I like to watch people who aren't PBA members bowl just to see the differences in form. Youtube can be both a place to explore this and see some really... well... less than successful forms
