I have been fishing many years without a shanty or tent, but have two kids who I think would fish with me more if I got a tent or shanty.
I just love my Shappell Widehouse 6500. Large enough for a person with 2 kids. 80" tall. You can carry it as a back pack.http://shappell.com/iceshelters/widehouseserieshubs.html
I think all the hub styles would get condensation.80" is plenty tall if you ask me. The Doors are big and as said easy in and out.
I've been thinking about buying that shanty. My biggest concern is, does it get built up with condensation while running a heater. The heater I plan on using is a tank top sunflower and it puts out 10,000-15,000 btus.
