The sport league I'm bowling in over the Summer starts May 19th, but only runs for 6 weeks at $20 a week. 3 man teams, winner gets a paid 5 man team entry into the world team challenge...something along those lines. I've bowled on the sport shot many times before and it's always ruined me. If you have an ego and don't want to humiliate yourself, stay away from the sport shot. If you ask me, it doesn't get any harder than this. If your spare game is there and you can toss a few strikes in with it, then you should be alright. Avoid opens at all costs because you can't count on coming back with an easy 3 or 4 bagger to bail yourself out. For an average, I expect to average between maybe 175 to 185. If I somehow averaged any higher than that, I'd be grateful. If you're not used to focusing completely on each shot, then get used to it if you wanna try the sport shot. All in all, bowling on a sport shot will turn you into a better bowler if you stay focused. You should be able to hit a mark and hit it consistently time and again. Also, throwing plastic hard and straight is the way to go when it comes to the spares on this.
