A-Game, thanks for the suggestion. Here's an update; I used the #3 sole with the radial heel tonight for league and didn't have any problems other than the natural adjustment to different-feeling shoes. After about 5 frames I was in a comfort zone.
I did start to get a little buildup on the heels again tonight, but I don't think 3 games is enough to cause me the problems I had in practice, which started around the 4th game, and I only was bowling on 1 lane, not a pair. I did notice the other guys sticking a little more than usual though, so I wonder if there was still a small amount of buildup on the approaches. However, no one complained about it so chalk it up to coincidence. I think if I just clean my heels regularly after each 3 game session, everything should be ok, especially if I am bowling on a pair and not just one lane.
Also, we needed to split 4 points tonight (3 games, 1 total pins) to win the quarter, and we got skunked by 100+ pins in the first game. It was looking like another choke, but we came back to win the next 2 games by under 20 pins each to take the quarter! Me= 628. Nothing special, but I am proud of it because one of the lanes had been destroyed by open play earlier in the day, and although we were bowling on fresh oil, the left lane had horrible carry down compared to flying backends on the right lane. I had to throw 2 different balls on two different lines all night! U Solid on left lane with a more straight line, U Pearl on the right lane with a little swing. Crazy difference in the two lanes, but we pulled it off! How did your night turn out, Mike?
