I use weatherpack connectors for everything on my ski as well. KEEP IN MIND-I only ride saltwater 2-3 times a year. I have found a lil di-grease does good, more di-grease does better, and tons of di-grease and my stuff always looks like it did the day I installed it.
Mick, I got to say, the setup you have now should be water proof, air tight, and possibly even bomb proof. lol
It looks like you went waaay overboard, but waaaay overboard is what usually seperated the people riding vs the people repairing! Looks good to me! The biggest advantage i see with weatherpacks is-I can pop my hood and take a tube of di-grease and in a manner of a few minutes, I have all the connectors packed full of grease again. (routine maint for me).
