depends what type of hot you're considering...if you're open to suggestions,i think a copperhead is a good choice(i have seen these guys run the gammut from dog tame to pretty nasty,even more personality variation within this species than other n.american pit vipers....but they don't 'ride' a hook as well as say a crotalus species(large/'true' rattlers)...lol,yeah have fun working with nerodia,or racers/whipsnakes for that matter,lol....i mean you may be in for a long 'training period' waiting to tame or master a nerodia...but yes i agree that racers and whipsnakes are similar in movement and temperment to elapids(fast,a little nervous/high strung)...yeah definitely get the hook(s),tongs,and safe enclosure ready before you get the snake,too...btw to ask if there's a non-hot that is a lot like a crotalus-fat,ambush type predator,not that fast,but with such good strike speed and range is sort of an oxymoron,i know of no such snake.however i do have a couple pine snakes that do a damn good atrox impersonation....if you are gonna go with an eyelash viper,something close to them? i think a tree boa/python is a good choice(never worked with either,but you can get some tree boas for relatively small $$(think amazon tree boas)-in fact green tree pythons are dropping in price,i've noticed...besides,these boids (esp. the chondros and corallus) are truly beautiful and apparently interesting/challenging snakes in their own right-but challenging in a way that you can't die from,lol...their personas can be feisty/unpredictable enough to keep you on your toes,too,a will their long teeth...yeah like others said,always keep in mind,there CAN BE as much temperment variability within a single species of snake as from person to person....hope this helped,good luck and be safe
