I demoed the VCTF97310 and the EZAI98 a while back. Really wanted to like the Tour F, but besides a great cosmetic, never gelled with it. I actually got the Ezone Ai for my wife to try, but when I hit with it, she said I hit much better with it than the Tour F. Felt much better as well ( to me, at least ) .
Ended up with two closeout Ezone Xi 98 and haven't felt the need to look at or try anything else.
As always, YMMV.
