I think I may try the grip puppies - I'm not really happy with the shark skins. They leave an uneven gap at the seam (which is a design problem - since they're wrapped around the grips there's always tension there at the velcro), and they're a little too narrow for my taste. Feels like I can only put my hands in one position now.

The grip puppies look like a good solution, at least for the rest of the summer. At $13.65 shipped they're worth the risk. Eventually I think I'll go with the gloss black Kuryakyn grips with weighted bar ends - but that's something that can wait until the riding season is over.
