Assuming you are running the same oil weight as last year the stiffer spring should need a bit more rebound damping and maybe slightly less compression. Hopefully you have that info written down somewhere.
I had 7wt last year and was running 5 clicks out rebound and 12 clicks out compression most of the time. I would have switched to 10wt to get a bit more rebound damping, but found some online info that the compression valves have really small holes. I was concerned it would make the front even more harsh so I stayed with that.
If I was to do it again I would stick with 5 weight. The harshness bothered me more than the lack of rebound, so I would probably have ended up at 3-5 clicks out on rebound using 5 weight. Compression probably 10-12 out.
When I had the cartridges apart this winter I was surprised how small the holes were in the compression piston. I am sure this is why I experienced the harshness when trying to use slightly thicker oil.
