Compression & rebound settings are based on so many variables (including the oil weight - which is lighter than they recommended) that no-one can give you the correct ones for you, you just need a base and then to go out and find what suits you best. I've found it helps to go out with a mate and get them to adjust the settings without you knowing what they've done, ride like you normally would and see if the ride is better or worse then rinse and repeat until you're there. Personally I think static / rider sag is all well and good but I would stick a cable tie on one of the legs and adjust preload to the point that in regular riding you are using most of the travel but have about 10mm left in reserve.
I recently upgraded my 13 year old OEM springs (and oil
) with K-Tech 10NM and 10W (as recommended) and found the difference to be pretty noticeable, that being said I'm "big boned" and the OEM springs had probably long given up the ghost. You seem to have pretty much replaced like for like so I wouldn't be that surprised if the difference was subtle, but it should be noticeable.
