Denial,
Well since this is my first retic I am not going to deny your claim. I have been around many large retics and in my little experiance with them they do seem more active outside of their cage than most but inside I have not experianced alot of activity.
I absolutely love how inquisitive mine is when I handle him and he is probably my favorite animal right now. I cant wait to see him with a little size on him.
I may go foe the 8 ft cage not sure yet. Since he is a male he probably will be ok in a 6 footer. Planning on stacking 3 high for him, my boa and a To be announced other yet lol...Leaning towards granite burm. I kept burms years ago and really enjoy them too and back then the granites were out of my price range
