Nope, for once I'm not being a sarcastic @sshole. As Tbird said, Blendon Woods in Columbus has 10' diameter asphalt "greens" and many of the holes also have gravel around the asphalt. Usually it's a premium plastic only type of course, but it was perfect for a torture test.
And the results of that torture test:
I played 18 holes, throwing 3 discs off the tee, 3 approaches, and 3 putts (I had to work on getting to know my new Theory as well).
XF1 continued to be a tree magnet, and as such it is majorly deformed at this point. In addition to being bent out of round, it is showing significant wear on the bottom and some damage to the overmold. This plastic is only slightly more durable than DX, and is probably not something I'd spend the equivalent of "Pro" or "X" money on unless I planned to have it be a pure putter. As far as flight goes, this disc is now a hyzer-flip machine. Blendon doesn't offer any wide open holes, so I'm not sure how the disc flies when thrown flat but it flips up nicely from a hyzer release and has a nice glide to it.
XF2 did not have as many tree hits or long approach shots that hit asphalt, so the fact that it's in much better shape than my XF1 disc probably means very little. However, this is the blend I prefer as far as feel in the hand, and I'm hoping the softness will lead to it being just a little bit more durable than XF1. This disc was still hooking up and dumping hard left at the end of 18 holes, but not quite as hard as it did when it was brand new. It's a very reliable, rangeable disc, and I'm hoping it doesn't break in too much farther.
XF2 is (IMHO) the better of the two formulas. I said it before and I'll say it again, I LOVE this mold! It needs to be produced in Electron and Neutron so that we can enjoy the out of the box flight for a while before the disc breaks in.
This is a fair point. The XF1 is a neutral putter at this point, and the XF2 is more like a Pig or VP in that you need to putt with some speed in order to keep it from falling off left before it reaches the basket. Both formulas grabbed the chains nicely, even on the cold windy day I tested the disc.
