Who boy (girl), you're in for a big surprise. Forget everything you ever thought you knew about bowling; it's a completely different game now. For starters, if you miss high, you move left, not right. I know, it didn't make any sense to me either.
If you can afford it, do yourself a big favor, and take a few lessons with a coach. It will save you beaucoup time and money. Let the coach advise you on which ball to buy, as the choices are now completely overwhelming. You don't currently have a "game" to speak of, so although we could offer some suggestions, you really need someone to ease you back into the game, especially if your goal is to once again be a competitive bowler.
Welcome back, and good luck. If you check my profile, you'll see that I've been traveling the road you're about to set foot on for the past three years.
BTW, the leather jumpsuits were simply smashing!
