All of the above are good suggestions. It's certainly nice not to have to grip the paddle too hard to maintain control. I personally use athletic/hockey tape for this but I have pretty calloused hands. IMHO oval or indexed shafts are actually counterproductive however, for 2 reasons. The first is that, unlike a euro blade that is dependent upon the user for it's trajectory in the water and has to be held firm to not flutter, a wing with good technique will fall naturally into its optimal angle of attack at the catch, and this actually changes throughout the stroke. Having an arbitrary index on the shaft basically doesn't allow the blade to seek out this optimal angle and instead encourages one particular blade angle that may not even be close to optimal. I can think of at least 2 paddles with ovalled shafts where I don't feel the oval is at the correct angle for proper use of the blade. Lettman Warp springs to mind (blade is fine, paddle is almost unusable cuz they whiffed on the correct oval angle relative to blade) Not a huge fan of epic for this reason. Moreover, a common misconception is that the lower hand needs a firm grip on the paddle. I find that the opposite is true, the top hand is the firm one that drives the paddle during torso rotation. The bottom hand can/should have a looser grip in the fingers that allows the blade more leeway, not a grip where the shaft is buried deep in the palm as this doesn't allow a "feel" for what the blade angle wants to do. many wings work well with a more open AOA at the catch than the oval/index seems to take into account. I've personally never become disoriented and not known what the wing is doing b/c of not having an index. In short, IMHO, tape is good, racquet grip is good for tactile purchase on the shaft, the o ring idea is great so your top hand doesn't slide down the shaft, but index-oval is actually of little benefit on a wing paddle, except as a comfort to those conditioned to having it. I think with some wings it's difficult to unlock the full potential of the blade unless you allow it to follow it's natural course, whatever that may be. or at least allow yourself to experiment a bit.
