Handling really depends on the individual I have a friend that handles ALL her Ammies just fine as well as her GTPs, and ETBs
That was my reasoning too, we have 2 arboreals that we dont handle as often an 3 others that unless they arent in shed and havent eaten are held a couple times a week.
In the end keep what you love, arboreal husbandry is a piece of cake once you get going. My GTP is in an exoterra screen top front opening which is 24x24x36 (LxWxH) and my Ammie is in a tub that's a good size 2.5ft x 2ft x 2 (LxWxH)
