Yep..I have a few bags and have used them for both smallies and largies. I've had some good success with them. Sometimes, changing from a tube to a bait like an Erie Darter can really get the fishes attention. I really think fish can become conditioned to seeing a particular bait (especially when you are fishing one area pretty hard) and a change to a bait with a different action and profile can, at times, be the ticket for getting these fish to bite.
darters rule. they work great with a jighead. they are sweet to pitch into cover. they rock texas rigged and pulled across the bottom. but one of my favorite ways to fish it is to rig it like a soft jerkbait and twitch it around shallow grass. those grooves move a lot of water when you work them on there side. give it a try.
you might also want to call kd outdoors in waterford. i know they carry poor boys there, just not sure if they have any of the darters yet.
Mike's RX Baits in Morenci, MI carries all the right Poor Boys stuff for Erie & St. Clair. His site is being updated, mikesrxbaits.com but call him at 1-800-856-5814, he'll hook you up. (no pun intended). I know for a fact the Wonderland tournament was won on custom color Erie Darter's from Mike's last year.
