neptune, you still having luck on crappie??? dont know if you remember me but i was living in whitefish a couple winters back and loved trying to catch those guys. you used preserved minnows huh??? i would always use forage minnows with soft tails. i made one trip last year since moving to bozeman but my brother caught a pretty nice one.
Icebugler, I haven't targeted the Crappie exclusively, caught a few out on Mcgwin iggers slough through the ice, but haven't been up to Blanchard this year(went in the fall and caught quite a few).
rigging preserved minnows: I just use a small 1/16th ounce jig head(Usually black or dark green) and rig the minnow just like you would a twister tail or soft bait. Then just jig it like you normally would, this usually works when nothing else is working...
