For the last few weeks I've been experiencing problems very similar to what I reported here
a few months back with the Rapture irons. 1 pixel mishits are resulting in shots that can go between 10-15 yards offline. I realise that these clubs have less forgiveness that the Rapture clubs, but still this amount of deviation has to be a bug in the system. The normal deviation factor for 1 pixel mishits with these clubs is approximately 3 yards.
I just tee'd off on #8 Bethpage, didn't move the aim point, and a 1 pixel mishit to the right on a 3mph head wind resulted in a shot that was pin high, 11 yards to the right. Please have a look and see if the same bug that plagued the Rapture clubs is at work here as well. Thanks.
