I purchased the Geek Golf Little Bastard - Rebel without a COR driver with the Boomstik shaft a few weeks ago but only recently was able to get to the range to test it. I was pretty sure I ordered the 9 degree but received the 10.5 degree. Be that as it may, I went to the range to try it out. Being a hacker, the head shape didn't inspire confidence, as previously I have gravitated to head shapes with a bigger footprint, but those concerns all disappeared within the first few balls hit. This thing is looking. In the past I'd b lucky to hit the base of the range fence but now I'm hitting the fence close to the top... and it was a cool 48 degrees out, so I would expect the ball not to travel so far. The trajectory was booming but not ballooning or distance robbing. I'm guessing I gained about 15-20 yards... under cold conditions and using range balls. As to dispersion; I was able to hit several right down the pipe. I pull hooked a couple and faded a few but none of the slices off the planet that I had hit previously with my previous Cleveland Turbo driver. It's all kind of counter-intuitive but it works. I think I would have realized even more distance if I had received the 9 degree but am fairly happy with what I'm seeing.
