This review has a caveat: My swing is in a pretty good slot right now and I'm scoring well. so confidence is high right now.
So, I was gifted a Geek NB head - 10.5 grey model. I wanted to try a heavier shaft (I've been playing 48 to 55g driver shafts lately) in search of lower launch. I bought an MCS 75 Blue driver shaft because it was heavier and mostly because it's BLUE. It's REALLY TOTALLY GAYAZZ BLUE (and it was $12 + shipping)! The goal was accuracy, lower launch, lower spin and shitloads of runout. I cut it at 44.75" and took it out today for an 18 hole league outing. I had a whopping $3 on the line, so the pressure was intense. The club was obviously heavier in total than the featherweight Cobra FMAX Superlite that I've been hitting weather balloons with. I didn't bother checking the swingweight because some expert dude said that swingweight is uninteresting.
Anyway, the unit performed as intended. Most of my shots were struck in the center area. I missed 2 fairways today and both of those shots were leakers that faded a bit too much. The other shots flew low to mid trajectory and were very straight. Runout was scary long and I had some shorter than usual approach shots today. Feel and sound was different. It did not have that "I smashed it" feel, and I'm guessing that the tip is probably stiffer than what I'm used to. Sound is "solid" if that makes any sense, no loud "tink", but not that muted Titleist/Callaway/Cobra sound either.
The clubhead looks square to me at address and not very long from face to back. Nice DEEP face lets me tee it a various heights. I was surprised how straight I was able to hit a non-offset head, so this is a bit eye-opening for me.
I'd say the shaft is a good value and looks great (to everyone except spuzz). I think my long drive today was 240 (which is super long for me but I'm betting it was 50 yards of roll. All-in-all, it's probably no better for me than any other driver available past or present, but with the accuracy and flight, it's a very good unit for my current courses.
I'm going to keep gaming it until I'm bored or it fails me.
