Yeah, you can sit down and putt while you nurse that sprained ankle!
That's not the real reason I replied, but it was a close second!
I just bought 4 identical Discraft Soft Banger GT's - same weight. I read a putting article in disc golfer that explained the concept of practicing continually with a bunch of identical discs, and preferably, identical discs to the one you want to putt with in game.
And yeah, didn't do so hot in the tournament in Fort Wayne IN this weekend...did decent for my level and time playing, and it wasn't last, but I wasn't happy with a +11 round 1 and a +12 on round 2 (albeit, round 2 course was tougher and longer holes).
