Has anybody ever used for them for walleye fishing? Pro's/Con's on them?? Just curious about them, seen them at a "bug" supply store. They claim they are "hearty" crawlers, more so than the canadian crawlers and can withstand higher temps.
Any info appreciated!

I have used 'European Red Worms' for crappie and found them very temperature tolerant. I would think they might be a bit on the small side for walleye bait but you don't know unless you try! I inadvertently left a package of europeans out in the shade for hours with no ill effects after about 4 hours on a hot day.

The ones I found were about the size of a pencil, round wise, and 4-5 iches long. Another name they call them is a carolina crawler. I may buy a flat and see how they work this coming walleye season. They say they are quite durable, I guess I will found out?!
