Phil,

At the moment, I'd just go with the GP 10 size retracts - they are small and light - great for this model. Fit perfectly on my Deception 15. The only thing is they have metric struts (2 mm) so you either use a metric wheel on a bent strut (for the axle) or you'll need a coupler at the axle junction (2 mm internal to 1/8" external) to attach 1/8" axles.

I used the GP axles (GPMQ4279) like the ones in the first photo but I'd probably use the DB ones (#613) in the second pic - just a little cleaner and I think lighter.

David.
