Summer is a really busy time at work for me. Thus, I haven't had time to look at forums, and I didn't even know a new disc was in the works. Until two of them showed up on my doorstep! I managed to sneak away for an hour today and do some testing.
I'm forehand dominant, but do manage to throw backhand drives once in a while. My noodle arm can only get any real distance with a champ monarch (anything else is too stable or too fast). The 419B had the same flight path, but was consistently 25-50ft farther with no more effort. Very pleased so far.
As for the 420B, well my long game is all forehand. I've been rocking the same Z Force for 5+ years and would quit golfing if I ever lost it. The 420B was getting very similar results with that awesome vibram grip and feel. Definitely need to spend some more time with it though. It is the first and only vibram I've been able to manage forehand. (ascent, trak, ibex are nice when thrown well, but wildly unpredictable for me)
Also, I hate all the super wide rim drivers. Can't use em. Glad neither of these are super wide rim.
The 420B replacing the Force? Well I guess that is alright, but that would mean the NukeOS might stay in the bag. Hmm, this is all getting confusing to me. I am still very excited to get my hands one of these bad boys.
