My straddle putts have always been weaker than my regular putts. I normally do a staggered stance and rock my weight from one foot to the other, but when vegetation forces me into a straddle situation, it's always been a disadvantage in my game where I can't do that.
So this winter with my basket in the basement (I'm blessed with a bunch of space), I have the PP360 distances marked off and I'm playing a game almost every day. For the ten putts at each station, the first five are my normal staggered stance putts and the second five are straddle putts.
After 14 games so far I've noticed a big improvement already with my straddle putts.
I like the point system in PP360. It places added pressure on the first and last at each station for bonuses. Since putts #6-#10 are straddle putts, I'm rewarded with a few more bonus points on that #10, giving me added focus. It's working. I wasn't getting enough pop on the spin of the putter prior to now, plus I'm getting better at focusing on my hand going straight up the pole. It's helping me to cement the muscle memory in place. No, I'm not great at using my knees for this (ala Keven Jones) but my 25-30' straddle putts are much stronger and deadlier than they were before. Hooray! I know for sure I missed two 20-foot straddle putts this past season in sanctioned tournaments that I likely wouldn't miss now.
