Congrats, Jake.
Remember that the STing comes with what seems almost a gloss polish and, even though it's a particle, it can get a lot of length. The TR comes what is supposed to be 800 (US) grit matte finish. All reviews say it is even reacting, BUT on medium to medium-heavy oil. BJI liked it a lot more than BTM did, implying its overall hooking strength if not in so many clear words.
If you want a little bit more length, take it to 4000 grit (2000 US grit)Abralon, by first using a 2000 grit (1000 US grit) Abralon pad on it. If you have Valentino pads, they have a 3000 grit (1500 US grit) that may be an ideal in-between for you.
