Hi,
first of all there is one thing to say: Stop comparing a wlp with a ball python! They are definitly not comparable in any way!
If you just know ball pythons for now, it will be sort of cultural shock. That's just to keep in mind when asking about wlps.
Ok, now lets see: Young wlps tend to digg in the substrate so it wouldn't be a good idea to use a head pad that is not secured. Adults will perhaps mess up the whole cage in the first couple of days. They will spill the wather out of the bowl, moving hiding places and all. You should think about this when providing things to your wlp. If it is enough to once mist the cage or the damp moss I can't say. It depends on your cage (size, material, heat isolation...).
You assumption is correct. I have six wlps, and just sold the last of ten off springs from 2004.
If you get bitten often depends on the animal and the way you handle it. If you are fast enough to grab the snake without gettin bitten you may be lucky. But hey, these animals are lightning fast strikers! If you have stressed animals or wc animals I guess you can expect the snake will strike at you every time, but as there are also some animals around that are less alert than others. You may have luck with one of these. But as a general answer to you question: Yes, it will happen every time. You better wear gloves.
If an adult wlp bites you, it hurts. It sure does. They have about 150 theeth, the first 2-3 are quite large.
More aggressive when young isn't unusual in any snake species. They simply have more enemies and have to defend themselves. But I have some young ones that woun't even try to bite me when I grab into the cage. By handling the snake frequently some can be tamed, others will never do good in captivity. As I do not handle any of my snakes often, I can't tell you if they will tame down for sure.
A general answer for discussion would be: Wlp's do not like to get touched anyway. Handling a wlp is totally different from handling a ball python. It will be a quite new experience! Most of the wlp owners I know will refuse to handle their wlps often, because they will stress out quickly. Another thing to keep in mind is, that they are very sensible to RI! If you can't provide mid 90°F over the day and the low 70°F at night and high humidity you will kill your snake in a little time.
Cheers,
Wulf
