I've still been a 2 piece user for some time...
I've been using a hall/sakic curve on an AK27 and a ST which are both low->mid kickpoint but my RS blades for sure helped make it seem to pop lower.
I picked up the Stasny curve which is the same as the Sakic/Hall, in a N11 from Costco which seem to be almost like the N12, as they weigh the same in specs.
I have to say, I'm impressed... lots of "Pop", especially in the blade.
Very good feel to the blade and shaft, never missing a pass... BUT I think what people are saying, especially with the non-grip, is a feel on the finish that isn't up to par like the high end RBZ/TotalOne.
I think its cause its non-tapered, and has a finish-clear/coat simular to the old Sherwood Response RM9/19 sticks.
but otherwise I have no quarms over its durability.
I did buy a pair and I switch between the two to increase their durability...
in fact "shaft" wise, the load feels very simular to the old RM19 pro-stocks I had, infact the same kinda shaft size as the Blue series. HOWEVER the blade feel is night and day, as the old one felt like super heavy fiberglass and dead, compared to this one.
