Given that there are now about ten* (marketed) disciplines of 'MTB', you're going to have to be a bit more specific.
On a front-sus bike, the HT angle changes as soon as you sit on it.
Add to that the fact that the arse-end of a Pomp is really quite short, and I'm guessing** it won't make the world's most surprisingly amazing XC/Cross ripper.
Waste some dough trying if you like though, living vicariously can be great fun.*sarcasm
**based on seeing nothing like it, at all, wearing front shocks
Isn't a HT angle around 70 rather normal on MTB?
