Your job keeps you fit, but it is hard on the knees and feet, I'd imagine. I am still a Telesteps user indoors because I was lucky and got a good one. The X&C is heavy to carry and slow to setup and fold in comparison. Why I like the Tele is this - I set it against the wall with 8 or 9 rungs extended, climb up two rungs, set the hatch aside, push out from the wall with one hand, pull two more rungs out up into the attic hatch, climb in. Coming down, push out, collapse two rungs, close the hatch, climb down. To fold it release the two bottom catches and the ladder folds up. Fast and light.
