I have one Revo 12.9 with a standard Predator Victory soft tip and another 12.9 with a Kamui Soft Clear. To put it bluntly, the Kamui tip sucks. I liked them on my 313-3 and i-core i3 shaft, but on the Revo they suck... The hit sound is klunky and it I have no feel for the spin. The Victory soft tip is the way to go, but I am going to try a Soft Kamakazi on the shaft that has the Kamui tip on it. I like the price and feel of Kamakazi tips on most of my shafts.
