Two things you can do to make the Deans Ultra connectors easier to live with: with a sharp soldering iron tip, "scribe" 3 or 4 lins on the four sides of the Deans plastic housing. Gives something to grab onto without adding bulk. Put a small amount of powdered graphite (lock lubricant) into the connector openings. It greatly reduces the force needed to work the connectors.
No pics, but if you need, I'll do some.
