Best M7 clutch kit?

[m7 carver]

Just wondering which clutch kit/kits work the best on an m7? It is a 153 and i want to do some clutching but dont know what to get.
Thanks!

I have a bikeman kit that comes with torsional secondary conversion on my m7 153" and it works very well in deep powder but the primary spring is fairly stiff so the clutch engages really hard which is not the greatest on the trail. I have not tried any other set ups tho.
