I've been wanting to try one out for so long, and soon I'll get the chance to see if it's right. That Scott Niedermayer blade I picked up is significantly lower than even the E4 or Montreal PC.
The curve is most comparable to an X28, but less deep: the heel to toe offset is similar to that of the E4, so it's not so hook-like. It's also a bit shorter than the X28, even a bit shorter than the E4 (in heel to toe length). My guess is the rocker profile of the Niedermayer will suit me better than the X28, but I've got to try them out first side-by-side to be able to tell.
