we have both 5 and 10 bowling here (Onatario) . I prefer 5 pin over 10 pin (smaller and lighter ball) I am currently i 2 leagues (Sunday and Wednesday nights). Average is down 10 pins from last season.
High game in 5 pin is 316 (perfect game is 450).
I love it and it is my one day a week to go out and have fun and not worry about my son. Although being just over six months pregnant and getting as a house it is becoming more and more difficult! The old people get upset if I jump up and down or get excited!! lol! But I have to admit in the last three months my average has improved 6 pins!!! So apparently this big belly sticking out in front of me is helping to keep me throwing straight!!
I can relate to this...my average went up 15 pins whilst I was pregnant. Guess I was putting more weight behind the ball !
Sadly since moving to a new area I've not had a chance to get back into league bowling. Maybe next season.
