Hi Quicktime,
The RDM cams are only for Turbo and Overdrive conversions, so unfortunately it does not look like the Reflex 3 will be the right sail for your current situation.
The Reflex sails use a different system of cams which are much larger and come in 3 different lengths. As yet, there is not much interest in an RDM conversion for the Reflex range.
you can see the three lengths of XL cams on the left, while the two types of cams used on the Turbo and Overdrive are on the right..
You should be able to get a Reflex 3 fairly cheap, so if you felt like a project it would be possible to fabricate some cams to fit an RDM.
Thanks
