So did I, and it is certainly similar. It's covered by the same patent, after all. The distance from the deepest part of the dip to the highest part of the nose was at least 10 mm longer for the Glider I had than for either TRK I've had. I've forgotten the actual difference, though - it might have been closer to 20 mm. Doesn't matter - I expect that dip to nose is the critical measurement that makes the difference between those who swear by the SMP and those who don't.
