I looked into this earlier in the season when I was in the market for a Dynafit-compatible boot, and could find only very little info. The new guides for stepping into the Dynafit toe pincers look interesting, and overall the boot looks like a nice synthesis of the best features from the TLT4 Pro and the TLT-700. <br>The most info I could find from any Euro or U.S. shop was from telemark-pyrenees, even though they don't plan to carry the boot. (Yes, that's how helpful tp is -- they provide more info than other shops, and even the U.S. distributer, despite not even stocking it.) Their understanding was that it's stiffer than the 700, but softer than the Mega.<br>
