Assuming you don't like two handers ( I have no problem with them ) you don't fix the problem through rules. Its an environmental game. You can put out lane conditions that are very challenging to any particular style. If you want to make a rule change ban surface alterations and require that all balls be finished to 4000 grit.
I had a bigger problem with the limited distance dressing rule of the 80's. That was a license to steal for every cup wristed hack who only had a general theory of how to pick up a spare. That bothered me because they could beat me without executing as good as me. Cant count the number of times guys beat me badly despite blowing multiple spares while I was picking up 10 pins.
Bottom line, tame the ball surfaces down, continue working on oils that hold up longer, and if high rev guys, including two handers can compete in that environment they have earned it.
Execution by definition is the carrying out or putting into effect of a plan, order, or course of action. If this cup wristed hack was beating you, he was executing his plan better than you were. I do not understand how people continually try to put people down because of the type of athletic ability they possess. It is a skill to impart revolutions and speed on a bowling ball, it is not something you can learn. Same thing with throwing a baseball 95+ mph. I am a one handed bowler, naturally sitting between 19-21 mph and 450+ revolutions depending on the pattern I bowl on. If I try to deliver a ball two handed you can cut those numbers in half, simply can't do it. That does not however translate to an advantage for a two handed bowler.
It is not a bowler's fault if they can throw a ball harder than you or rev it faster. I recently watched the PBA Super Clash again between Belmo and Rash. That was a perfect example of shot execution winning, all they talked about was Belmo struggling on short patterns and he made the correct adjustments to outscore Rash for the win.
The Sport of Bowling will not move forward with continuing attitudes that bowling was better back then. Why would people want to get involved in a Sport that is "regressing". The majority of people who do not actively bowl get their perception of Bowling through regular local league bowlers. In my experience, the majority of league bowlers have a "better than you" complex and people aren't worth the time to explain how "technical" our game is. The game is simple to get into, with a little time and effort easy to be good at, and if you want to be great you will need to put in a lot of time and effort mentally, physically, and learning the technical aspects of the game.
No offense to some of you, but you apparently just are not as good at the game as you would like to think you are. I know where I stand, I'm far from elite. I have my good days where I can compete at a high level, but I can sure have my off days as well. I'm ok with that, but one thing I will not do is make excuses about how someone else beat me(unless they are a sand bagger) especially based on the fact how they choose to deliver the ball.
