Default 05 500 sportsman clutching for less rpm

Has anyone modified their cluch and or driven with the goal of reducing rpm at a even (steady speed) cruise on flat ground.
I know most of you want more acceleration and top speed. But it seems to me that when the bike is just rolling along on flat ground the rpm could be lower.
My 96 400 2stroke, I ride around alot in low range because if I don't plan on going over 25 mph, it seems to make no difference in h or l the engine stills slows down
my 05, if it was a standard trans, i'd be giving it one more gear up and letting it lug more, there is a vary noticeable rpm difference between h and low for a given speed of say 15 or 20 mph.
The 96 seems like it can be going slower then 7mph without the belt slipping in the clutch, the 05 you can feel the belt quit sliping right @ 7mph, the bike jumps ahead a little and the engine slows down a bit.
I think Polaris did this just to get the maximun effect from the EBS
I see no harm in this, as the cvt can shift back to a "lower gear" if the load or throttle is increased.
Hopefully the clutch would stop slipping at a lower mph in Hi, and i could run a little farther on a tank.
BTW, how far are you guys getting on a tank, its along way between fuel stops up here and I was hoping the 4 stroke would out distance my old 400.
The bike has excellent acceleration stock imo and plenty of more than enough pulling power in low.
I have a tandem 5' x8' ATV trailer and have hauled 1000lb 30.5 by 32" "forestry special" tire or 150 US gal of diesel on the trailer without any trouble getting the load started.
