No regrets, because I feel I have made the putter better. I do regret installing the All In on a putters I thought were working only to decide they're not for me. Buy another shaft, rinse and repeat.
My course has one against a neighboring town. I was invited to play this year. 18 holes at their course (best ball, alt shot) and 18 holes at ours (best ball, singles).
I'm not sure what you are currently gaming, but for me these were a pleasant surprise.
Distance is great off the woods, Irons even better, wedges are not bad with some good one hop and stop. Putter depends on the player, but like a softer feel.
