Rim tape

Velox creeps, rots, and holds moisture next to your eyelets so they can rust quicker. Also usually needs replacing if you break a spoke. Schwalbe blue plastic for general use, Veloplugs for racing. Some people like a belt and braces approach of electricians' PVC tape over Veloplugs, although I haven't tried it myself.

Building some XC wheel with veloplugs.
Partly out of curiosity,
partly because I may give tubeless a bash later (might even put the rim-strip over the top, depends on tyre seating),
partly because I may replace my disc-side spokes (revs with super comps) if the wheels dont behave.

They seem like a nice flexible alternative to me.
