I like the spring rate just fine. I have an aftermarketshock in the back [YSS] with a pretty firm spring there too, so overall some might find my bike quite stiff-legged.
I did the fork-stanchion zip-tie test after installing the springs to check on the amount of travel I was using, and it seemed ok - same at the rear, where I get surprisingly close to bottoming out, although the spring rates around 1200 lbs, I think.
The aftermarket shock is slightly longer than the standard one, so the rear end runs a bit high, and I pre-load the front to make sure it's not too nose-down.
It's the only bike I ride, so it feels fine to me, but someone who rides lots of different bikes back-to-back might find it steers weird, or rides too hard, or whatever. I like the firmness of it, but that's just me...
