The largest snake to bite me on bare skin so far was my 6' female a few years ago (my fault, I startled her). She bit my hand, since that was the startling appendage when I reached in to pick her up, and it did bleed and bruised a slight amount by the next day. It wasn't really all that bad, nothing like a cat or dog bite or even a cat scratch (all of which I've had the pleasure to encounter for comparison's sake). Other than her, the other large snake was my testy male - 7 footer - and that was with my gloves on (I knew he was VERY cranky that day, but his cage needed cleaning never-the-less). I only have a couple of snakes that I regularly use gloves with when first removing them from their cages, even with the use of a snake hook. The first is my female dumerils boa, which is a very aggressive feeder and strikes the first warm thing she encounters almost every time - then spits me out, and my female Solomon Island ground boa who is wild caught and really hasn't tamed down appreciably since I got her last year. Considering I have 23 snakes, I don't think needing gloves for 2 of them is all that bad.
The gloves I use are my motorcycle gloves, very snug fitting and very smooth, soft leather. I make sure not to pull away when they strike (gloves or no gloves) so that the snakes don't lose any teeth (which can and does happen). And for what it's worth, I'd take the snake in if I were in your shoes and believed I could provide it a better home.
