Mark(Fuscus),
In a word " Yes"
I have found from personal experience with water pythons that they can get a bit stroppy if they aren't handled regularly,their not as placid as carpets.
They can seem to get really territorial and a bit unpredictable, so the more you can get hands on the better, especially at the size they are now, when their bigger they will be more fiesty, so if you don't tame them up early you could have future probs.
Don't get me wrong, i am not saying that your snakes are not now tame due to one incident of striking with their mouths closed, just that in my opinion, the more handling with WP's the better.
Slight change of topic, I went to the Rosehill race course Pet Expo today, and there was an exhibitor there with a med sized water python, the previous owner apparently had left a large live rat in with the snake, and it wasn't hungry, what a mess it made of the poor snake, it looked like the last third of it's body had been bashed with a sledge hammer several times, the scars are well healed now, but very unsightly, I just felt for the poor snake, the agony it must have gone through!
