Been looking around... Crockett-1 and -1b have same profile as Highlander-732, just way better stats... only -2 and +5 PV respectfully...
The -1b is a Royal, and we know they do build SLDF mechs, Royal possible.
4, 4, 3 or 5, 5, 4 vs. your 3, 4, 3...
Now if you jump to a -732b it gives you 67 PV...
Everything you have listed, minus a single Urbanmech, leaving you 2 PV left. Higlander-732b and Crockett-1b... 5, 6, 4 and 5, 5, 4 damage, plus the rest.
