My issue with TBAC is that generally if I'm on the ground, and I need a little more height, I want to be able to pull out a notch or two. The spring loaded legs takes some getting used to. If you overshoot as in it shoots out too many extensions, you now need to basically get the damn thing to retract, and it doesn't quite retract well without some force.
I switched over to Accu-tac BR-4 G2 with some lightened springs to make the legs move quicker... and I'm also shopping for the Ckye Pod as it also has an easy pull down method of extending the legs.
