Well, personally I just put together some random bot pieces for my L sized rampage melee, as long as it gives me str and wlk stat
But if you want some precise names:
Default Baron BD: 15 str, 13 wlk, 18 tgh, 350 hp, 765 capa for you to work with after taking all capa
Machintlet BD: 15 str 12 wlk, 11 tgh, 350 hp, 800 capa
Mighty Byne BD: 14 str, 6 wlk, 16 tgh, 355 hp, 735 capa, + personal body shield
Daedalian BD: 15 str, 15 wlk, 16 tgh, 465 hp, 625 capa to work with
Thorla bd9: 12 str, 11 wlk, 13 tgh, 372 hp, 630 capa, built in boost run support
Gyllanbard BD: 15 str, 11 wlk, 15 tgh, 364 hp, 760 capa
Geograsis type-G: 18 str, 8 wlk, 18tgh, 356 hp, 725 capa
For LG, I mainly just use Achtsieben LG: 1 str 5 wlk 1 tgh, 60 cost 75 hp
But some of the other lgs I've used are baltheon, big mountain for their 90 hp at low cost, and Gaderoga LG for 5 wlk + extra booster spot
BS, AM and HD I've never really given too much thought, as long as they give me good str and wlk stat I'm fine, though Cosmo Kaiser am is one of the common choice for me for the 3 str and good hp
