marginal snow wheel kit?

[Viper S]

I've had good luck with the small wheels at the bend up front on my 121 Y sleds. Now going to ride the 136 again, and got talked into keeping 2 slightly larger wheels up front.
Any need to add more wheels up back? Sled has new Hyfax, but I don't believe its the new Dupont type. I mostly trail ride here in Maine in good snow area.
Happy T-day to all!

I was thinking, stll am, about putting a rear set on my 121.

I just don't know a 100% if there is enough room and/or if they will interfere with anything?

Dupont slides for next year though.
