If you're happy with the pens you use and simply want to avoid sweaty-hand related smudging, you might have a use for those 'smudge guard' gloves they make for use with graphics tablets.
They're designed to stop hand smudges without getting in the way of using a pen, and I don't see any reason why they wouldn't work as well for real pens as for digital ones.
I always thought they seemed a bit silly/excessive for their intended use of avoiding smudges on screens/graphics tablets when using a digital pen (could just be because I never really get that problem for some reason), but this seems like a legitimate case where they might really help: they'll be dry, and even if it turns out that the excess ink problem isn't caused by sweat or skin-grease, I imagine they would absorb excess ink before they smudge it.
The advantage over looking for a type of faster-drying pens is, you don't need to change pens from a type you know you like to a type that might not suit you so well.
Search for 'tablet glove' to find them. Also, 'SmudgeGuard' seems to be one common brand name.
Or you could probably get similar results by taking a pair of scissors to an old glove :-)
