Currently riding both MX comp on on Orange Vit T XC and Pushed Rev 462c on Cotic Soul the latter rig takes it no question, and I'm 84 kg.

I had 06 MX Comp ETA's ( still have on spare bike ) and there is no contest the Reba SL Dual Air wipes the floor of the MX Comp totally,  makes the MX Comp feel like a RST.

I'm outside the weight range for putting the Pike Coil + Uturn assembly in there sadly ( 29" fork so it fits )

Coils aren't a exact science though,  depends on how you ride,  11stone mate gets more travel in a street bounce test and in use on my forks and I'm 16stone,  he does the same to other bikes to.

GO COIL!!!

Perhaps it's horses for courses. Just sticking to 100mm travel examples:

A coil Marz Dirt Jumper (coil) joggles along trails but even a 49kg friend was getting 90mm travel on the BMX track last week. The Dirt Jumper is the perfect undercarriage for a jump jet.

Then there's the Reba (air). Buttery smooth, excellent tracking but it shoots through its travel on bigger obstacles - clung.

The Marz Corsa (air) doesn't impress initially but pick up speed and go flying into a rough section and all the travel is there, well controlled too.

Ohhh yes another 1 of them LOL

John,  put abit more oil in the Positive air chamber of your Reba so it ramps up some more if you've got that issue.
