Geppetto disagrees with you:
In the first minute he says it's CCM's P71, which is different from Warrior's W71 and also similar to but not quite the same as Malkin Pro, which is strange because that's right back to where we started: you were enjoying the W10 and he pushed the Malkin Pro even though he says he doesn't think they're that similar.
Also, depending on the Malkin Pro variation, the lie isn't that far off. W10 has that common pro feature of a radiused heel, for handling the puck a little further away from the body. One of the minor blade shape differences between my Malkin Pros (not sure they match with PSHS' Malkin Pro) and E4s is my Malkins are a little more square at the heel and the toe--not actually square just not as radiused as the E4--otherwise, the similarity is unmistakable. This will make the W10 read as quite a bit lower if you try and line up the heels' lies. But if you look at the blades overall, the W10 is quite flat on the last 85% of the blade, even flatter in rocker than the E4, which is close to as little blade rocker as you can find. These subtleties of rocker moments are what separate the W10 from my Malkin Pros, which overall have approximately the same lie. Both would be rated 4 under Warrior's old system, or 5 under Easton's pre-E28.
