So Im getting ready to buy a few flies from AFFG for the 2010 season and last season the few ESL that I bought from them worked pretty good. But right now im thinking about trying their articulated line of leech flies. I was wondering if any of you have used the articulated hareball leech flies. How do they rate in comparison to the standard ESL? should I consider buying a bunch of the articulated leeches or stay with the tried and true ESL fly? Let me know what you guys think!
