I've often thought of giving the crossed dipoles (I guess you call it a
turnstile antenna) a try on 75M since a 2 element yagi or quad there
might be a bit unwieldy :O Now if I could only remember the math
formula to figure the direction of steering by knowing the phase
difference between the feeds of each antenna.

A turnstile has a fixed 90 degree relationship between the two dipoles.
This makes it somewhat of an NVIS antenna good for satellite communications.
On 75m, a low dipole does approximately the same thing. If you are thinking
of changing the phasing away from 90 degrees, it would technically not be
defined as a "turnstile".
