I’m also new to this. Buying my first tub. Also landed on a Master.
Originally, was looking into LSX700, but went with TS 7.2 on advice of my dealer. The difference is about 2,500 for essentially extra jets. I’m already getting the stuff that matters - ABS pan, Mast3rPur, circ pump. Couldn’t justify that second for a few jets.
Take it for what it’s worth. Just sharing my experience.
