what is the heaviest iron hook that can be bought in the sizes above? I've been using Mustad 34011 to tie up heavy leeches without weighting wire, but want more heft and better points in situations where adding additional weight is a no-no. Any style is fine, any eye, but desire long-shank proportions generally in the range of classic salmon/steelhead irons. This ain't for the purdy flies fellas - its for the nasty leeches - so bring out your brutes.
