Thanks for the informatiin guys, i have been in contact with Kais and they do indeed do a 90nm spring with a free length of 230mm. Im just waiting in a price, and too decide if i actualky need it. After reading pleiades post, i had a rethink.

Then i want my bike to go trail riding too.
I Think i ask too much of a single set up.

I have projection 4 way dog bones set at 15mm (to. Match the added height of WP fork conversion. Could this have an effect on leverage ratio.

I removed the shock last night and added another 6mm preload, (quicker than doing 1/28th of a turn when fitted) and seems more like a reasonable sag, 70mm with rider.

This has imoroved all of the above riding conditions, so im sticking with it for now.
Thanks for your help guys, much appreciated.
