I use Ergon GP3 grips with the small bar ends from Ergon GP2. A welcome change of hand position, in those brief and rare periods when I don’t have to be able to rapidly throw the anchor out.
Having said that, I am using Joseph Kuosac bars which are a bit wider. I had Ergon 2 on original M bars but had to shorten the grip so that everything would fit.
Which turned out to be highly unsatisfactory.
