Thanks again Gnarly Dog!
I thought I saw this idea on your blog a while ago :-)
From looking at your retrofits, it looks like you put the toggles pretty far at the ends of the kayak? It looks like one of the holes were drilled near/on the deck/hull seam. Have you noticed any odd issues because of this? If I were to follow a similar scheme - I would be putting the toggles at these locations?:
I was thinking of looping the line through the toggle, binding the 2 lines together so I don't accidentally put a finger through them and having a bungee holding the handle taught on the deck. - it looks like you have one line connecting to the toggle - any issues with balance?
