Kileaua fork length

[oldave]

My '97 Kileaua is currently running a SID Hydra Air up front. I want to go rigid to fit proper full length grds for winter. I have an unused Project 2, a to c 410mm. Will that noticeably/adversely affect handling?
Incidentally, while I can find no stamping in the steerer I have seen the original 2007 sales invoice which says "3x butted". What weight would suggest that it is a 3x version?
Thanks.

410 is correct for that year and weight should be under 900g for TB (with normal length steerer).

Thank you! With uncut 260mm steerer I make it bang on 900grm. Seemingly v thick paint, including most of steerer!
