supermoto sag settings

Because it's too cold to ride, I have been playing with my rear sag settings on my 2000 Husky sm610r. I've looked around on smj and found anywhere between 60 and 100 mm rider sag with 25% free sag. I had been riding it with 100mm but my free sag was 35mm on the rear. It felt really stable like this, but also quite heavy with little feedback or feel from the rear when leaned over. So anyway, went to the stiffer end with 62.5mm rider sag and 15.6mm free sag on the rear. I am hoping for a crisper feeling in the turns with more feedback from the rear. I haven't messed with the front at all because I like the front end the way it is. Although, I'm sure that will change, maybe.
Just looking for feedback , pros and cons of running stiffer vs softer?
I also rode a 04 ktm 525sx w/supermoto wheels that was probably around 40-50mm rider sag, but thought it was a bit of a handful.
Not really gonna ride it on anything but the street ( asphalt )

Generally speaking.....

Sag does not change your spring-rate.

What it does is position the suspension at the right place in the stroke
whith the rider on board. It also affect chassis attitude when adjusted.

In the end, the most important thing is front / rear balance, the bike needs
to respond to inputs in a balanced and even fashion on compression and rebound.

You see a lot of different sag setting in supermoto because of the different riding styles. There is not going to be a be all end all setup for everyone. Being that you don't plan on any dirt I would tend to think going towards less sag would be a good start. Like Tom mentioned there is a lot to be said about proper spring rates for rider and bike weight. Also you mentioned comparing your bike to another, that is tough to do. What tires were on the KTM, size profile and rim width? Same with your bike, that is not even taking into account geometry.
