Need help with kids set up

[TRST]

My son is turning 12 this summer weighs 100lbs and just got intrested in the course last season.   He is running 26,28,30 mph.  We have a 64" HO CDX and a 65" Nomad. What speed does the equipment start to make a difference?  What kind of set up do you have kids of similiar size and skill running?

I would say that either ski will work.  I have a son turning 11 this summer who weighs 125 pounds.  Last year he was running the course on a 63" HO Odyssey which is a wide ride class ski into 30 mph in the course.  After nationals I got him a 65.5" D3 X5 and his best was 4@ 32 mph on that ski.
