My shot is medium most of the time, but it was very dry last week. I threw my trooper and had a good look but couldn't carry the seven. I was thinking that I just needed something a little stronger. I just found out that another fellow lefty bowler friend of mine, has both the reactive and urethane hi flare. I'm going to watch him throw them tonight. He revs it more than I, but I should get a good read of what it will do for me. I'll keep you posted.
