I am a veritable god with zip ties....
First impressions had me slightly more impressed with the design of the eskimo latching mechanism. But clam seems to offer a touch more in the way of accessories.
I like the idea of being able to have a table/cup holder, rod holder, etc up off the ice, but still in arms reach while in my 2-man hub, out of the tub and off the ice. I like to fish in comfort, but when space is a hot commodity, comforts are sometimes negotiable.
I guess the big question is how well they actually work, do they impede the fold up or storage of the hub while collapsed? And second being, what do people find the most useful attachments are?
