After spending a couple of months last summer alternating between a rigid and a 5″ travel full sus, I found the rigid a good opportunity to work on my finesse and floating over things, whilst travelling at the extra speed I’d fooled myself into thinking I could go at by riding the same trails on FS. Then back onto the FS where I’d then go even faster having gone nearly as fast on a rigid, so figuring I “must” be able to go faster…
So if I was you I’d keep it as it is and enjoy the “moments”.
However, if you’re not liking the effect, just up the travel. I don’t think 1″ (or 3/4″ once you’ve taken out the sag) will make a huge difference to the feel of the bike – it will be noticeable but not completely different. I’m sure you’ll find there’s plenty bikes out there that would still have much slacker angles than that. If you’re concerned though put adjustable forks on and if you end up finding it doesn’t bother you then just leave them fully wound out.
