I have never been on 6m, however as I understand it there are different
types of propagation and the angle is different for each type. If it were
me I would place antennas at various heights from 30' up with switching
and phasing and see what works best for you.

I'm currently doing the ground work for getting a decent sized 6 meter
setup for my new QTH in KH6.
I'll be using around a KW and have homebrewed some copycats of the old KLM
7 Yagis for 6.
My only problem is being a rookie on 6 is I really don't know what arrival
angles are most common for six meters for distances of greater than 2500
miles, which is the minimum distance for 99% of all contacts from KH6.
Height recommendations are pretty useless since the terrain is nowhere a
normal terrain due to the extreme drop away from the tower site. Even a
combo of 20 over 5 produces enormous gains at 1 and 2 degrees.
N6BV's terrrain analysis only provides angle info for HF. Check the
arrival angle on 10 meters for various places and then check 6 meters..about
the
same, as his program wasn't meant to do VHF arrival angles in conjunction
with HFTA.
I know no number will be THE correct one, but a ball park range of the
most common angles would be a big help. I plan on giving as many USA
stations
KH6 for the WAS as I possible can. The same is true for JA and hopefully
some EU guys as well.
Any help?
