I use 7610s on my Nortons and have been happy with their behavior in the 40 to 80 MPH range I generally ride in. I agree that the damping adjuster is difficult to get at and becomes less difficult with the seat knobs removed, however, once set I haven't found it necessary to revisit the adjustment. I don't set the damping until the the shocks have broken-in which I do as part of the 500 mile service.
The Ikons, on my current build, are paired with a set of the Consentino cartridge internals up front with the NYC Norton low sticksion bushing and seal kit which is new territory for me. I'm hoping that the shocks and cartridges work well with each other, but I'm prepared to upgrade the shocks if necessary. I use a clover leaf off a freeway where I can bring my speed up in increments until the suspension begins to misbehave and then start making adjustments. The beauty of this is that I'm always close to the speed that was safe, so a light touch of the brakes restores stability.
I have had, on various motorcycles, Hagons, Ikons, WP, Wilbers and Olins. The Wilbers/Olins are amazing, but at the speeds I ride at (have gotten down to) don't give a viable value proposition. WPs are pricey and on the edge of the price/performance border; if the Ikons don't play well with the Consentino cartridges I'll go there.
Best.
