I thought that tip was especially helpfull for larger quilled feathers. Since I don't normally tie small flies the quill size and affect it has on the aerodynamics of the fly is not normally an issue for me...and I have lots of left over hackle tips. Being the scrounging, tinsel hoarding flytier that I am, I was happy to see a solution to my pile of ziplocs.
(at least a partial solution that is.

Thanks again for passing along some great tips Al.
