Revalving Fox Float R for a very light rider

I'm using a Fox Float RP3 on my daughter's full suspension bike .

I've got a couple of these Magicshine clone lights. The both have an XM-L led emitter but the controllers are a little different.

My daugther's 24" FS bike came with a Suntour SR coil spring fork. The spring rate was quite good for my daughter's weight but the fork had no noticeable damping and was almost 2.1kg....

This version has the following vital stats:

Rotor Rvolver boost front hub weighs 110g.

VPone hank pedals - 180g - 'carbon' body, single sided, not sure how these would work. Light and cheap ($30);
