If all you are ever going to do is use it for a Jig pole and not casting any of the cheap plastic line holder reels will work. I have underpins on a couple,WM small bait caster. On one and a couple of spinning reels on others. The secret to me is getting your pole balanced where it docent wear you out when fishing for long periods of time. Take the rod you are going to fish with and try several reels on it even if you have to borrow some from buddies. The ideal setup is it will balance with your finger next to reel mount where you grip would be.
