No worries mate, sorry I can't help on the compatibility. Spring weight is heavily dependent on your own weight, but also on intended use ; as an example, I weigh around around 215 pounds at the moment (fat bastard !) and use a 9.5 kg/mm on the track. I'm told that may not be heavy enough, but as i prefer a sift spring it seems to work well for me.
All the best,
Do not walk behind me, for I may not be leading.
Do not walk in front of me, for I may not follow.
Do not walk alongside me, for the path may be narrow.
Just piss off and leave me alone.
