I LOVE pips. I never had a problem with them. But first, you have to turn them in with line tight. If they are loose, they will overlap. Then, don't pack in too many. Always start on one side and work your way to the other in an order (I normally to top to bottom at an angle). If you have the originals (I have about 7 of them, and about another 12 newer two models) they will turn the easiest actually. The ones with the sticker lids are normally "sticky". Problem is NOT the lower case. I found that if you grab a top off a new pips (the clear ones) they will turn quite easy. There is too much of a suction effect and lock up. But the old original smooth ones turn really easy. The second generation (with the slotted sides, but sticker tops) would stick. The newer ones are pretty smooth. I have only had an occasional problem with mine. Those were if I dropped them and some hooks popped up or someone borrowed a leader and grabbed from the middle of the pip.

But myself, if you want to get rid of any, I'll take them. I'm not shy. lol. I use all of mine, have different setups in them all. But have some of the very original ones. They are a white plastic with a raised letter lid. And quite a few different generation Pips. I've used the leader wheel and the styrafoam ones. Hell, even used a wetlock corrugated one (wetlock is the waxed cardboard for any laymen out there lol) and they worked fine. But I prefer Pips.
