3:1 2 blade heads

[Justin Falon]

Which 2 blade heads (other than Grizzly) are 3:1 ratio???

[deadpool]

I think stos and howard hill heads  are 3:1

[Orion]

HH are, STOS aren't.  Few heads are actually 3 to 1.  One of the new heads by Abowyer get's close (the Brown Bear).  I believe the new Ashby head is very close as well and may be 3:1.
