Experimental shape prototype, and questions (2015 update)

Thanks for all your input guys! ;D
Actually I’m a little disappointed that I scrapped the protruding rims too,
but it really felt noticeably uncomfortable in hand, I wanted the design to look
cool, but competition level playability was also a big factor, which led me to the current design.

I’m currently making some minor changes to it since I’ve yet to measure the weight of
the bearing/axel/pads. The 2 halves weighs(according to the program) in at 64g without the guts and it
might end up at 70 with those added in, so i’m probably shaving a couple of grams off.

I hope to get the final design to the machinists within the next few weeks.
