It's just the regular Mashie. They have them on TGW for about $70 and I ordered it when they were running the 15% off deal, so it was really a steal, IMO. I actually have not even swung a Mashie plus. Is there a big difference between the two versions? Once I figure out which driver I want to use (and hence get down to 1 in my bag...), I may consider adding another Mashie hybrid.Rob which one are you using? Mashie or Mashie+
I think you could easily go with either the M3 or M4 rather than both.
As for RBZ comparisons, I only have a couple things that I remember. First, the RBZ felt really head-heavy to me. Second, I didn't hit in nearly as well as the Mashies. That's a personal thing and only based off one range session though. I do think the rails and the keel on the Mashies are game changers. At least for me they are. Great performance from a variety of lies and you have a little more surface area at the bottom if you miss thin.
