I use Prolink Gold as well and started using it in 2005. I prefer wet lubes and I apply every 100 miles and wipe the chain dry. If I've been in the wet, I wipe it / clean it with WD-40 on a cloth first. It's not that I don't like the cleanliness of wax, but I honestly don't think it lubes as well; it can't flow back when displaced and I don't want to buy new chains so often. On a 3700 mile cross-country trip on singles in the summer of 2005, the leaders wanted us to put on new chains at the halfway mark. The leader measured spoke spoke wear and it measured like a new chain, while the dry lube chains in the group very definitely needed to be replaced. However, not getting black greasy marks on hands and legs is definitely a plus for dry lube - maybe I should try the dry lube for a set of chains and see what I think.
