I would say that the HA runs at about 69-70 degrees stock and the SA is around 72 or so. What happens next depends on the travel settings as well as what forks you put on it. The old girl is a lot steeper than the current gen of slack bikes, which I think explains her popularity in the hands of those that have experience riding short and fast bikes.
Stick some photos up and that'll help ID the year. Keep it short travel and fast if it's an older non VPS model!! 140/152mm i2i shock gives just under 4" travel. Interesting that Commencal and Orange are really pushing their 4" travel bikes just now for trail centre use. It's like suddenly people are realising we've been going longer and longer travel and it's more than is needed for aggro XC/all day mountain biking.
Just shout if you need more info if it's an older one.
Yes and no. I am in the camp that says travel is physical size dependent. At 6'3" 5-6" works much better for me than 3-4 ever did.
I like 5 - 6" travel, because it's plusher in the initial part of the travel.
That really helps with trail vibration on our super chunky terrain.
It also gives me some "screw-up" room. You know, like when you dive into a drop too quickly and / or there is a big rock at the bottom.
I freely admit though, that my bike isn't as nimble as one with shorter travel.
It is however one of the nimblest 6" bikes I have ever ridden, even with the high BB.
I'd like to try a 6.5" shock, just to see what the difference is.
