It's all good bro, I need to lose this pudge I put on in the past few months haha. I'm pretty off the cuff myself usually, so I don't take much personal. The width thing is why I'm going to cut weight for one, and two trying to keep it under a 160. With the TRS the width is shown as the same on the 155, 157, and 159, so that's why I figured well might as well snatch the 159 if the width is the same there. The Cobra and SL would be the same width as the TRS at 158 in those boards at 253mm. The Goliath is 254, but honestly 1mm is a hair's difference.
I really do like the fact for the groomers that the goliath is a cambered board for the most part with tbt. The part I'm worried about is the so called "delay" I've read about with edge transition with my already small foot. In the pow I'm not too worried about it, with the rockered corners on tbt it shouldn't be as bad as the rental planks I used to plow with.
The TRS is sounding better and better though, hmm.
One more comment (and you might know this already): Waist width only tells you so much. The sidecut radius will affect massively how wide the board 'actually' is (both at the bindings and the contact points).
Normally people look at width where the bindings go to make sure that the board is wide enough for their feet. For you the analysis is the other way around: Making sure that the board is not too wide throughout.
For instance, compare the 154 TRS with the 154 Banana Magic: Almost the same waist width (actually TRS 25.3 vs. Magic 25.2) but because of the smaller sidecut radius on the Magic the board is already slightly wider at the insets and considerably wider at the nose/tail (29.8 vs 29.2).
Similarly, if not quite as extreme, comparing the 155 Cobra with the 157 TRS you have got narrower waist width on the Cobra (25.1 vs. 25.3) but a slightly wider nose/tail (29.5 vs. 29.3)
