Just echoing what others have said here. The Throttle Rocker helped my right hand a lot. I have some gel gloves, but have been wearing the protective gloves lately. I have a second pair of cloth gloves (the cheap brown jersey ones you use for gardening, etc.) inside the leather ones, and that seems to help slightly. I also have some gel grips on the bike.
On the C10, putting some ballast in the handlebars (such as tiny shotgun pellets) helps reduce the buzz. I thought C14's didn't buzz nearly as much though, and I don't know if the handlebars are 'hollow', like they are on the C10.
Getting away from the death grip helps (which is why a throttle rocker is so nice). When commuting, I rest my hands around the grips but don't grip. It only takes a fraction of a second to grab, which is what you are going to do anyways if something causes you to pucker up...
What I found worked really well was duct taping bubble wrap around my grips for a long trip, but the bubbles break down. Someday, I may get the foam grips, but the buzzing has been tolerable of late (it lessened as I broke the bike in over the last 35,000 miles). I feel almost no buzz at all with my ski gloves (with insulated 'foam' gloves inserted), but that's a LOT of thickness. Plus, it's warmer now, so the ski gloves stay home.
