As promised: I bought a couple of O-Rings 28ID x 5mm and put them onto the grips. Feels much better for me (with my fat fingers) than the spongy grip puppies, and the results IMHO are better to look at as well.
Installation is 5 minutes per side. Just roll on the o rings one after the other until done.
Here are some pics of the progress and the end result:
And the finished product:
Quick and painless, and at about $10/side not too 'spensive either.
