Last week: Fri.....267, 238, 182....687
sat.....276, 214, 165....655
Ive only shot one 700 this year, averaging in both leagues 210
The shot does breakdown, but when I release it right it no problem. It just seems that come that third game, I start dropping the ball and chicken wing it and miss to the outside. Im not sure how to get myself more energy. Im not even old..lol 40 yrs old, in decent shape...
