Wow, it sounds like you are really down JW about this..
Mate, realise that everyone was once in your bowling shoes as they begun bowling in their respective leagues.. I'm sure your team mates don't care too much whether u bowl great or not, if they do care about the winning of the league and money/trophies, then find another relaxed league.. Or practise in phantoms leagues or just open bowl until you feel u are ready to rejoin a league..Do u think that perhaps u are more worried about your scores than what your team mates are?
Social leagues are about having fun and enjoying your bowling..They generally aren't too full on...Unless it's a money league (man, people get real upset over the old dollar)
Re your splits, I'm currently getting quite a few splits at the moment.. My game is getting back to where it was, so I accept that this is normal, work out why u are getting these splits.. First thing I do is look at what is happening as the ball enters
the pocket... Is it too heavy, too light, how are the pins hitting??
Envy, one of the 7 dadly sins isn't it!! Forget about it JW.. You will get those rewards, so it didn't happen to u your "first" ever year of bowling.. Guess what, I got nothing for about my first three years, and I also use to think why can't I get some kind of award/badge/trophy, other newish bowlers seemed to get things..I admit I suffered from a bit of envy myself... Now after I have worked at my game, more than them working at their game, my ave,high game,high sereies have moved far beyong theirs.. Things work out for the better. Your'e a keen and improving bowler JW, don't sweat it, it will come, probably much sooner than myself..
Take care, keep your head up mate.
