I just ordered some pre-coded tags with custom bibs for an upcoming race from
runvirt.com. Super nice folks and they sent me samples ahead of time so I could test. They do not use foam on the chips, rather a tyvek label/film or something like tyvek that is supposed to be moisture resistant. I have always ordered custom bibs from Race Result and bought tags from Atlas and coded myself and cut my own custom foam strips. But after comparing the cost, and seeing the quality, I like what they are selling. I think I paid .46 per custom bib/chip coded. (I only purchased 300). Even if I decide I need foam and still have to add that, this is still a win for me, because it saves me a ton of time. The one thing we never have enough of. Tim
