I got enough play with my Jawbreaker Bangers today to give my opinion. As far as durability they are passing the test. I've gotten in 5 rounds today with them and they only have minor dings that I would say are similar to new KC Pro and 350g plastics have had in the past. Absolutely nothing like the Pro-D and Soft-X Bangers that I used before. After 5 rounds with those plastics I swear 4-5 grams would have been beaten out of them already. I do wan't to point out that I only putt/approach with these Jawbreakers. I don't throw them off the tee. I have a Ti for that. I would also like to note on the tackiness of this plastic. Really feels comfortable in my hand. Nothing slick about them even though they have some firmness. If there is a Discraft putter in Jawbreaker that you like I highly recommend getting them.
