For longlining jigs, we use primarily the BnM BGJP's. They work great and are reasonably priced. Sam Hearings are good too, but you're stepping up in price a little. And yes, for out the side, you need staggered lengths if you're not going to use planer boards. As mentioned, you wouldn't typically want bottom reel seat as they won't go in most rod holders. If you're wanting to longline cranks, you'd probably want to step up to BnM PST's.
