It's funny you mention these PIPS. Last year I fished with Jigman and what did he pull out of his vest, you got it a pips. I had to laugh 'cause I hadn't seen anyone using one for years, I didn't even know they still made them. I started using a leader wallet made by XSTREAM that consists of several ziplocs sewed together with a velcro strip. This allows me to tie 36 leaders with corkies,aeroflys, yarn, and barrel swivel all kept neat and tangle free.
