I don't like anything with a step sticking out of it.
If you fall, even using a fall restraint, while climbing your ladder, you can get a step underneath your ribcage for your efforts..and that might leave a mark, among other things!
I like Rapid Rails...I leave two up on each stand, and take the bottom two out. That way no one can climb the stand while I'm not in it, and deer (read that BIG BUCKS) can't walk up and smell me on the ladder while I am away.
two rails weighs maybe 4 lbs, go in with me on my backpack, and I can put them up with a strap in less than a minute.
Big shoes aren't a problem, slippery shoes arent a problem, because it sits AWAY from the tree like a ladder, and your shoe is enclosed by the rails. You can get 20 feet up with a four piece set of rails so even you nosebleeders will be happy..and they are not too expensive.
