Congrats on the purchase of the TX. I am about to pull the trigger on one myself.
One thing only alluded to briefly is that the TX takes a 1-piece Z-liner which overcomes the problems of cold spots like the 6-piece style. It also attaches with velcro along the entire length of the hammock which seems like a pretty good method to me. (I wan't sure about this so I verified it with Clark). So that makes the Clark Z-liner a good option when considering bottom side insulation.
