Yeah, once you don't thoroughly mix a compound that hard packs, you're kind of screwed. I've always been partial to M-F which, with a few rockings back and forth of the 5 gallon jug and you're good to go for the day. It's been a while and do believe there are others out there now that don't hard pack. For swimbaits (of course depending on size) I always went with their medium. That's what worked for me.
