There is a difference between boids and colubrids, as you pointed out. My BCI likes to "stretch his legs", too...so to speak. I often find him laying flat across the front of his viv, or stretched out along a branch from floor to ceiling. Very rarely have I ever seen one of my colubrids laying flat out unless they were moving from point A to point B and I interrupted them...then they "freeze" in position...otherwise, I don't see them stretched out. And as you stated...we are discussing size options for a corn, not a boa. I wouldn't dream of keeping a boa in an Exo-Terra front opening viv beyond the first couple months of it's life...they exert FAR too pressure on the glass walls, and I am fairly certain they would pop open the doors on one of the vivs fairly easily. My boa and my BP are both housed in 29gallon critter cages, at the moment...I do have a 4 1/2' viv set aside for my boa when he gets a little bigger. My colubrids are all kept in racks. I am comfortable with this because of the lack of "excercise" and stretching I see in my colubrids. I am confident that they have plenty of room in 32quart Iris tubs in their vivs, where I wouldn't dream of putting my boa in one...even a larger one. He explores too much. The BP...possibly in the future, but...right now, she is happy in her 29.
Also, as regards space and stress...it isn't a myth. Certainly ground cover helps, and as a snake grows into the viv, they become more comfortable. But I have personally witnessed issues related to(I am assuming) vivs that are too large for young snakes. A young lady brought a hatchling corn into the shop just the other week that wouldn't eat. She had it in a 20long with plenty of ground cover...fake foliage, climbing branches, 4 coconut shell hides...far more ground cover than I provide for my own colubrids. I took the snake for a couple weeks to get it eating, and when I put it in a smaller enclosure(a 5 1/2g Critter Cage), it almost immediately "perked up" and ate the first offering I gave it. This leads me to the conclusion that stress IS an issue as regards the size of the enclosure. And this is not the only instance I have seen in this regard. I have helped other people by having them use smaller enclosures to "relax" their snakes.
It's not always about moving in confidence...it is often about observation. If a young snake cannot see a majority of it's habitat while in hiding, it can get stressed out. A smaller tank allows the snake a more overall view of it's "kingdom" without exposing itself. Naturally, this is going to help the snake to feel more secure...
