Ok, so I personally have only tried the Smart Hockey Tape in the garage, on a shooting pad, so my opinion matters little. But my 15 yo midget AA son have tried the tape in 6 practices and 3 games. By the end of the experiment, he told me he was going back to regular black cloth tape, pretty much saying SH tape sucks.
I paid $15 for what I thought would be 3 rolls of SH tape, but to my surprise, 6 rolls showed up, in two different shipments.
My kid taped his pretty much brand new Vapor Flylite 65 Flex Int (his second Flylite), the same way he normally does (it's actually more difficult to tape than regular cloth tape) and you sorta have to stretch the tape to make it taut and the very end of the tape (for us, ends at the toe since we tape heel to toe) almost always will not stay on the blade. He takes a strip of cloth tape to wrap around the toe to ensure Smart Hockey Tape doesn't get unraveled.
Feel: the smart hockey tape is almost a tad too thick... feels like it does give a slightly better cushion while receiving puck but my kid thinks it's too soft and doesn't feel crisp. He doesn't notice the SH tape being any stickier than regular cloth tape.
Weight:: This was the dealbreaker for him as he did not even use a full roll of SH tape and you can already feel a noticeable weight differences vs regular cloth tape, almost making his Vapor Flylite feel off-balanced.
Durability: Another big minus. The tape job fell apart after 1-2 practices, starting at the bottom of the blade. The ice is not kind to the rubber tape and just shreds the bottom up BADLY. Regular cloth tape lasts him waaaaay longer and never falls apart at the bottom, and even if it does wear at the bottom of the blade, the tape job doesn't completely falls apart.since cloth tape seem to stick a whole lot better than SH tape.
So he never really saw any benefits to using SH tape and frankly, neither did I. We really want to like it but we just can't... it's really nothing special and the tape needs to be a lot stickier to last longer on a blade.
