I want to know where you plan to ride at 12000 feet with a 3/4" track, especially when you weigh over 350 pounds
Just kidding that was all sarcasm.
Sorry dont know jack about turbo clutching but couldn't resist.
TTT for ya

thats the way it goes when one lay out the facts to good 
I am partial to the 20/50 supertorquer 2 speeds but the supertips will work too. It,s just that the 2 speeds are so easy to tune & dial in. Do you have a preference on what weight you want to use?

No ,im open to all suggestions.
I have heard that Nytros are belt eaters when they are turboed.
Should a more shallow helix be good to help that problem ?
What about mcx own weights ,are the any good ?
Sorry but what is: 20/50 supertorquer ?
/thanks.

Eating belts is usually a result of bad clutching.
Using too steep a helix without enuff secondary pretension is the cause of that.
20/50 is a weight made bt supertorquer.
Check out their website.

I don,t know anything about the mcx express weight as i have never used em. I am sure tho they have some good set ups.

I have been running the 60g supertips for two seasons, which seems to be a good starting point for tuning the MCX. I run the 230 kit.

There are soooo many factors for a clutch setup, there are no setup thats best on everything!
For scandinavian driving, both on and off trail, where off trail is boondocking/treeriding i would suggest 14.5mm rollers, blue/wh/blue and supertips or heavyhitters.
45° helix with Yamaha white @ 60°
or if you boondock alot an cat purple @ 70°.
This works pretty good, but i've seen Nytro MTX's blowing belts regardless off tuning and cooling if boondocking a really long time without letting the clutches cool down.
