rods
Crappie are obviously light biters and weak fighters so id step down and stay with a bluegill rod. With smaller fish id rather have a little more give in the rod over backbone. I would say a spring bobbers would be essential but not necessarily have to have one that comes with the rod. Some members have said good things about HT ice blue rods for sensitivity and very inexpensive.
I dont have a st.croix so i can say but i would probably get an UL and then a L.
I dont ice fish but use ice rods and i kind of like the the 30" rods for a little extra spring. I do also have a berkley ML that i do like also.
