I’ve used a few, but came back to a Summit Viper believe it’s the SE model, which is aluminum like the SD, but much cheaper due to generic camo used. It’s not licensed mossy oak, etc. which I could care less about.
I look at it this way, the time to pack a stand back in and limited days to hunt has me focusing on the rut which means all day sits. Nothing is better than summit for comfort which is a must for all day sits.
