I added the single Crescent soft handle to the rear of my OG Lite Tackle like you did. The centered handle makes it easier to load in my truck. Thanks for sharing.
I just added the cam strap handle to my ck1. I don’t need a stand assist but it’s long enough on a Ck1 or Ultralite to be one without moving the handle location. Using the handle on the Shoalie and liked it enough to put on my river boat. Might even put one on an Ultralite.
