Thanks Tony! The serration design improvement is pretty apparent when you see them side-by-side like that. They seem to be a much tougher design, no little teeth, etc. I'll be getting my hands on some rope, hopefully, and doing a little comparison between the two. That'll be after Christmas, though - because the RC3 is still wrapped up as my present from my wife... I made sure to get that photo-op before I let her take it away from me, though!
