Also check out Carbon Arms Pinwheel for shell caddies. I moved from Invictus to CA last year and absolutely love the Pinwheels.
Nothing wrong with the Invictus at all, I just prefer the CA. I use the load 2 method and the CA really seems to hold the shells well when running around.
I purchased from Brownells in the States as nobody in Canada had them in stock when I was looking. Not cheap but IMO worth the money.
