So what's the general consensus about speed EVs?
I assume adamant is the way to go, but what are threats you wanna hit first? Coz some HP investment seems important for sustain
I think this question is big and you got only one answer so far. I've been wondering... Is speed investment that important for Bulu? I mean, is outspeeding a handful of mons that necessary in comparison to what HP or Def/S.Def investment brings to the table?
This thing is a self-recovering killing machine, but without the proper defensive investment, it can be OHKO'd or 2HKO'd by a large number of mons. Also, the frailty of the "speedy" set severely limits the number of switch-ins, and that's a huge minus considering you'll want Bulu to be hammering the opposition as frequently as possible.
In my opinion, outside of Bisharp, Bulu doesn't get that much of a disavantage by being outsped. He can tank a hit and go for Leech Seed/Horn Leech.
Simply put:
Speed investment Bulu: glass cannon with mediocre speed. Shit longevity.
Bulk investment Bulu: powerful pokémon with solid defenses, albeit slower. Good longevity.
I think people underrate how tanky Bulu can be. He ain't got a great defensive type, that's true, but there are some mons who can form a solid defensive core around him (A-Muk and Toxapex come to mind.
