It wouldn't be a good choice for your Heckler because it's really a 7" fork with a travel reduction that's only designed for climbing or long, smooth pedaling sessions. You really shouldn't run its travel reduction for real active riding. It's not designed for it like some other "wind down" type systems used by Rock Shox, Marz, Fox, and even other Manitous.
That fork is a darned good fork, even though I'm not a big SPV fan on a fork. I think it's better than a Minute, but that's only because I think a Minute is almost an XC fork...just my opinion. I think a Heckler needs at least a 32mm stanchioned fork for best results.
BTW, some Breakout Plus forks had TPC+ instead of SPV. Just curious about the one you're looking at.
