I'm like John I like a wide gap hook, particularly in the smaller sizes. I usually tie on the Tiemco 2457 caddis pupae hook, they are 2x wide and 2x heavy. I like the heavier hook because I want the fly deep in the water. I have also tied on the straight shank hook too. At times I will tie on an up-eye hook too, like the Tiemco 206BL.
I really don't think that it makes that much difference. Just tie some up and let the fish be your guide.
