When it comes to an out & out carry contest crankers have an advantage. Strokers/Tweeners are traditionally more accurate and generally bowl better on tougher/tighter conditions. I say generally because there are always exceptions to the rule.
Good point up to a point. This is the same conversation we've had for over 20 years now. What has changed since then is that you don't get conditions where a cranker can't get a urethane or plastic ball down the lane. (Yes, that really happened sometimes. Yes, it was butt ugly.)
In my experience, strokers in Australia are not much more accurate than crankers. They squash a lot of late 4 pins, blow 5 pins, get wall shots and throw brooklyns. What's their excuse? People aren't born crankers. My first league average was 114 and I bowled conventional with a slight backup. Then I saw Chris Batson bowl and had stars in my eyes. It was all bloody hard work (good fun too!) from there.
That said, Tonx is on the money. Every good player of any single participant sport (bowling, tennis golf, etc...) requires an "A" game and a couple of threads to it that allow them to be more competitive when the "A game" is toast. Cranker, stroker, tweener, whateverer. Even so, the "grind out" condition is usually a euphemism for a bad lane surface. Ex-PBA Lane Maintenance Director Len Nicholson once told me "You don't get big scores from a bad surface." Enough about lanes, this thread is about styles of play.
As for carry competitions, I've never been a fan of the term. These days especially, bad carry is indicative of sub-standard shot making or equipment choice. Strokers and fudgers (there's more of the latter) have
never had it so good in terms of carry. It comes in a box about 9x9x9". The trouble for them is, crankers with higher revolutions can sometimes open up some area on the lane. This is a function of precession (change in rotation) and reading the surface friction. Higher carry then occurs because the crankers simply have more angular velocity on the ball surface when it hits the pins.
They've put the extra effort on it. They've lost a bit of accuracy in the process (a lot in some cases

), they cop some horrific splits and washouts in the effort to find a line. But when they do,
some people complain that it's unfair! It's like complaining that the big guy next to you in the gym has more muscles! He put the work in! The ugly side of the "unfair" argument is that when everyone else is shut down (crankers, lefties, people who wear loud pants...) these same folks talk about it being "tough but fair." Bowling is never fair. It's probably not possible, unless we move to an oil free environment (use some type of dry lubricant like silicon), which ironically, would kill the crankers forever through over-reaction. But maybe then, it could be a level playing field.
