Any bowling people,here??????.

I to am Lefty.. I bowl Weekly with my work team.. Been doing it for the last 5 years... This my sound crazy to some but I took some lessons and it changed my game... I took the lessons because I didn't want to be the worst bowler on the team.. When I started bowling I used to throw a 14lb ball as hard as I could and right up the middle.. Best game was 187 back then and I carried a 121 avg.. After the lessons from a olympic silver coach he changed my style completely... Now I throw a 15lb hook ball and last year I placed 97th in the state of Colo. using my handicap.. First time I ever competed.. I did have two days of (LUCKY) great bowling and came out with a 197 avg.. My avg for the most part is anywhere from 171 to 189 in the last three years.. With my best game to date is a 287.. It was the luckyest game I have ever shot.. Even the bad balls I thru the pins all fell down... onecatnodog
