Bob, once again I might have a suggestion here: http://gnarlydognews.blogspot.com.au/2009/06/sea-kayak-grab-handles.html
I like to have my toggles at the end of the boat where surf wet-exits will not harm my hands if I am holding onto the kayak (best if kayak is held by bow/stern than sides).
I like the retractable end toggle to prevent pesky banging of handle: http://gnarlydognews.blogspot.com.au/2011/02/shop-retractable-grab-handle.html
