Funny, all my best series and bowling is in practice. My joke is that I am the best practice bowler of all times. All of my 800's are in practice, never done it in league. I have two 300's in league, probably a couple dozen in practce, heck had three the same week practicing last year and think I barely broke 600 that week in league. Seems my biggest string was like 27 or 28, last 8 or 9, 300 and then front 6 or 7. Of course in practice, league no where close. Outside of the scoring issue, I always look for practice to help perfect something. In the last year or so, that has not happened. I have been in a slump that involves both the practice and competitive aspects of the game. I keep going back to the lanes and trying to find that natural swing and timing. When it clicks, I just hope it stays for a while.
