I use wet lube on tour. I tried wax based drip lubes in the past but they needed more frequent re-application than wet lube. After a couple hundred kilometers the chain begins to squeak. On a tour I don't have the energy to be lubing every 1.5 days. Wet lube gets me 3-4 days of riding.
The chain is a disposable item. I don't get why people take the time to hot wax immerse their chains. Your chains lasts longer, but by the time you add up the cost of the wax and all the time you lost, you're losing money. Take that time and do a few hours of overtime at your job. You'll come out way ahead in cash. Put it another way, the faster your entire drive train wears out, the fast you have an excuse to upgrade.
