I love my spinsanity, only thing missing is a stock to make it fantastic.
Before you re-glued on the rubber did you happen to try and put a nerf dart threw the flywheels?
I didn't, but I think it would be possible. You'd have to build a loading mech from scratch though...
Great write up. Was the spinsanity on sale at a local retailer, or on a website?
I picked mine up off of Amazon for $12.99 as part of a larger order (Hmm..., one more item and I get free shipping. How about the Spinsanity) I've also seen them on Target's website for the same price.
