Enve specifies that ONLY Enve rim tape can be used on their wheels' so that's what I use for my 3.4 AR rims.
It's thicker than other rim tapes, so it takes a little practice (you have to pull very firmly, and just do 6 inches at a time). But it makes a perfectly smooth bubble-free, rubber-like surface when you get it right, and it definitely seems higher-quality and more impenetrable than other rim tapes.
Very expensive, but like most Enve products, it's worth it.
Obviously it's cut to the proper size for Enve wheelsets, but it also works well on many other rims. The tape seems to have just the right blend of adhesion and flexibility to get a great seal.
A+ product, and the variety of widths is nice as well. It would be nice if the # of wraps per rim would be specified, but that is easily searchable.
