I am planning to order legs from Siever's for my 2' x 8' layout and they come in 40 or 48" heights. I initially thought the 40" would be plenty tall and I could sit while operating the layout, but after reading some older forum posts, am leaning towards the 48". It seems that 48" would put the layout at a better viewing angle and allow easier access underneath to work on wiring, etc. I think I can find an adjustable stool if I want to sit down while operating the layout. Any thoughts or advice will be appreciated. I a 6' tall if that makes a difference. Thank you.
