right, My Pace RC 40s seem to go through there travel a bit fast, what would happen if i put one soft spring in one leg and one medium spring in the other, medium springs and i never got full travel, soft and they work but can bottom them out with a good hard push.

Try to find yourself a dual rate spring that's correct for your weight. That will give you a nice supple fork for the small to mid stuff but will ramp up the damping for the bigger hits and stop you from bottoming out all the time.

I mixed spring weights in a set of forks a couple of years ago and (altough to be fair it could just have been down to the fork) they floundered so I ended up going back to the firmer springs in both legs.

  fork tuning,,   one of the problems often encountered with forks is too much rebound damping ,

   on your static test the forks feel fine but over a set of roots the forks will eventualy run out of travel 

  the rebound is too slow the fork fails to return to it's full height before hitting the next root and this continues until you run out of travel or roots,,

  to test for this you need a set of nasty roots,, or lay a long ladder down on the ground and ride along at a reasonable speed and using your cable tie check out your max travel or if you are a techno geek like I used to be just use your data logger

   try varing speed to see if it makes it worse or better 

   you can use the same method to set up the rear of a full suspension bike  ,

   one other thing  i know it seems a bit anal but keep a note book for your bikes and note any changes made and effect  then you can go back  to a setting that worked over a course  ,,, the biggest problem i found in setting peoples bikes is they had no idea what changes they had made,,, since they last raced at a particular course  which meant starting to set up from scratch

  i could go on  but i wont bore you with any more

Notebooks aren't anal! Anal is what I do (something I picked up from a Motocross mechanic) I have a small square of yellow gaffer tape on my forks & shock & write the settings on that with a sharpie. Once I change the settings the tape goes into the top of the toolbox.
