That would be a really funny sight to see an edge with SKI's!!! I may go for it but i really hate freezing my buns off..
Anyway.. when i tryed balancing the hub on my last prop I used a lot of epoxy to add weight but, it ended to be too much.. Then i decieded to take some material off the other side and destoryed the prop.. I went to lengths and using silver solder in the holes on the back of the prop.
