I have a BTC Chimera MkI... it's awesome. Trigger response is amazing, and it's easy to set-up / program.

The MkII allows you to delete the anti-reversal latch and cut-off lever, in addition to the traditional mechanical trigger assembly. Thats alot less moving parts to fail.

I'd say the only drawback is data cables are very thin gauge and easily fail if nicked or pinched. As long as you're careful routing them, it shouldn't cause a problem though. The spectre eliminates this problem as there are no datacables.

Anything from BTC is well worth the 100$ IMO.
