2004 Kodiak clutching advise

Hello everybody. I have a 04 450 kodiak solid axle. Im a large guy(230ish) and do a wide variety of this with my kodiak ie plowing, mudding, high speed trail riding, pulling things. I currently have a 1mm clutch shim mod and larger ITPs 589s. I did a clutch service and noticed I need to replace my rollers and the belt the next time im in there. I dont mind a somewhat agressive clutch, but not sure the exact route I should take. Any info can help, thanks
