Never tried fishing with a spinner that way...

My two favorite lures for fishing weed choked lakes like that for pickerel are the Johnson Silver Minnow and Mepp's Timber Doodle. Pickerel will happily whack the snot out of either and they are both very weedless...

Also, I like to use a weightless plastic bait rig:

The weightless plastic bait rig is very weedless as well.

Rig it with a Zoom Tiny Fluke or another favorite of mine a Flash Worm

These lures will also catch bass, pike, walleye and others...
