In early March, I am going to a 1850
GT style tournament, for the first time I might add. Over the many years since 2007, I have amassed much in power armor and vehicles. I've participated in quite a few 1 day tournaments, and one local 6th edition bonaza that attracted more than 10 people.

So, I am no slouch and I hope that I know my codex inside and out.
However, local meta's being what they are, I have no clue what Tau and Eldar REALLY do, outside of the normal internet coaching. Neither do my local playing buddies. Not a single Ripetide spammer or an Eldar player even.
So, given a choice between army Bugs or army Blood Angels, I believe I have been given a sign, recently.
So, what Do
BA do that lives against the dreaded Tau/TauDar/Eldar/random flyer spam? My limited understanding is Tau only have some
Str 8 in 2 units, and Eldar have none, but lances? So, my rather large collection has 3 ways to go: Critical mass of power armor and Feel No Pain, Armor 13 wall, or a well rounded
TAC list that is rather Blood Angely.
List 1: Maximum Dudes! Maxed out troop slot. RAS marines,
Tac squads, and
DC and as much dakka i can afford in
devs and bikes. Around 50-60 power armored bodies seems hard to kill, even harder with Priests trying to keep them alive. Pods are an option so I don't slog forever. Flyers? Screw the meta, I have Dudes!
List 2: The Wall! Triple Baal Preds and triple Preds/Vindicators. Troops as needed. Double Librarians. Why? Because we still get to pick powers, and I need that 5+ cover save! Suck it, plasma!
List 3: Full Blood Angel. A well rounded list. Mephiston, Corbs,
DC, Pods, Frag-dreads and a Stormraven. Troops as desired, no idea if Tacs or RAS though.
Well, what has the "Best" chance of me having fun? Ha! Just kidding, I would have fun either way, but with those who have a meta that does have full cheese, will any of these 3 list ideas stand a chance? I would post a wall of text for the lists, but at this point it's list building for me.
