I shoot a roll-over. That's all I shoot (typically). While setting up, though, I keep the Euro-style option in mind (I only use the pull side and the quick-flip). It is only about 65% on target (I typically shoot it wide when I miss), but it has its place. Otherwise, I stick to my guns. I wouldn't advise spending too much time learning a new shot unless you are going to make the switch completely. I WOULD advise spending time working on your main shot and its options...you can never spend too much time here.
Bottom line: Stick to your guns. Work your main shot and forget the rest. After a couple thousand balls, you should be able to hit its options without needing a backup shot. Explore the shot's options, both in shooting and in set-up. Hope this helps.
