Has anyone tried these Veloplugs from an Australian wheel company as a replacement for rim tape? They do look interesting but are quite expensive at about $1 each. They are supposedly about 1/3 the weight of rim tape, but adding another $60 or more to a set of rims seems excessive. They look to me like they stick up higher than tape would, but they must not have caused too much trouble during testing.
