I think rain gloves run about $20/pair. I wish they sold them separately, as I never wear the other. It's somewhat of a waste for me, but a single rain glove will last me at least half the summer before it starts wearing thin in the upper fatty thumb portion. I use GP New Decade composite grips (top portion half/cord, bottom half rubber). I've yet to have an issue.
I just slightly dampen the glove before play... go to the clubhouse bathroom before teeing off, splash it lightly with faucet water.... you really don't need it soaking wet if you already sweat - it'll get damp enough soon enough.
The more moisture the glove has - the more tacky it becomes. Let me know how it works for you if you try it. Definitely made a difference for me in the hot summer months.
