I'm currently using these Talon Fly II's with SPD-M520's. The pedals are great but the shoes do have quite a bit of flex, I also made the mistake of getting them a tad larger than I normally wear.
Yeah I'm on the hunt for a new frame right now, I'm hoping someone will buy mine with the carbon fork for $350. At that point I have $600 to drop on a frameset, but this frame might not sell.
