Quality rim tape makes a big difference, as it protects the tube from being pinched by the spoke holes. Rim tape made of fabric (Velox is a common brand) works much better than the rubber rim strips that some shops use, as it doesn't stretch and get pushed into the holes like rubber.
Velox comes in a few widths; I used 17mm for my Open Pros. If you're not sure which to buy, you could either measure the approximate width of the area where the tape would sit inside the rim, or lookup a proflie (cross section) of your particular rim online. I think 17mm would be most common.
