I've not heard of using Kevlar sock on the spar, (normal TD or F3B, J gliders) but definitely Kevlar tow, or string as a spiral wrap. It has the qualities of holding the carbon spar caps onto the spars, (as its qualities are good in tension), when under bending loads. That prevents the cf spars from sliding / shearing, which quickly leads to spar failure under hi-g forces.

The kevlar sock should work well, but might be a bit of overkill if you are concerned
about weight..( but for ds'ing.. probably a good idea considering the bending loads)

Joe Manor, the DS'ing guru might have some insight into that..
