Clutch and belt

I am getting ready to do my 100 hr service myself. I plan to tear the clutches down and clean, scotchbrite, etc.. I have slipped my OEM belt a few times and just recently changed my tire/wheel to Maverick beadlock/bighorn combo, so I think I should replace my OEM belt and keep it as a spare. I have read for hours and can’t decide what to get. Gates G-Force (kevlar or carbon) or Dayco XTX?

Also, while I’m in there is the Dalton clutch kit worth doing or should I just save my money for a complete primary? I don’t plan to go any bigger than a 27" tire and I don’t do mud any deeper than tire height(and normally not that high).
