Which variator and belt should I buy?

I just bought an Eton with a 90 cc ported cylinder high compression head and wrh pipe. I need to replace the stock variator and belt due to wear.

I am interested in the Dr Pulley variator or a Koso but am not sure which to go with. Also, is it worth spending the money to get a kevlar belt? I am new to these cvt's so any advice is appreciated! The quad will be used for mx and recreational riding with the ocassional drag race.

Also, I am curious if anyone ever stuffed a larger diameter variator from a 100 cc in a 90 cc motor? According to the specs I found (see below link line 2 and 3 in the chart) the 100 cc variator is 105 mm OD while the stock 90 cc uses a 94 mm OD. If the 105 mm would fit that would translate into higher top end. I am just not sure it the shaft is long enough? It appears that there is clearance for the 105 OD.
