Fork size and handling

I thought I might be best off asking the framebuilding folks this one. I've got a hardtail mountain bike I'm building up that's spec'ed for 80mm of travel. For a rigid fork, the frame manufacturer suggests a 438mm fork, but I found a great deal on a 425mm fork.

I e-mailed both frame and fork manufacturers to ask if a 425 would be okay. Here's the response, in part, from the fork manufacturer: "The handling on the bike will be much twitchier and the BB will be lower and youll most likely clip more rocks with a shorter fork but you may actually like the more agressive position on the bike."

I know the 13mm shorter fork will change the handling, but will it be as extreme a difference as the quote above suggests? Much twitchier? Clip more rocks?

What do you all think?

Your bottom bracket will be +/-0.25" lower, and your head tube angle will be +/-0.5degrees steeper.

Part of it depend on what your actual HTA and BB ht are. If your bb is already at 11.5", there's no way I'd go any lower. If it's at 12.5", you've got room to spare.

What's the HTA on the bike "supposed" to be?
