[600MRG] Vertical or Horizontal - not really sure which it is

I am using a 160 Windom - 40 ' at apex, and each leg sloping down to about
8 feet above ground..it is fed with coax, and it doesn't have the usual balun, 
and coax isolation transformer in the line.. It's my homebrew special just to
get on the air a few years back..I wound 25 ' of coax onto a 3" PVC pipe for
the top, and dropped down 35 feet, and wound 25' on 3" pVC pipe, with 15'
left going to the radio. I can clip the center and shield together and
use it in a Marconi fashion with sloping top load, or I can use it as a low to 
the ground dipole with sloping legs.. I get the same amount of S-meter reading
either way, However I get noticably better performance using it as a dipole, and
Inductively Loading the short leg with a variable Inductor which I tune for peak
reception.. My curiousity is this; using it as a dipole, maybe referring to it as an
Inverted " V " , I don't really know for sure.. Is It responding more as a Vertical
in this fashion ?? I know that typically, if you slope the dipole legs, the antenna
performs more like a vertical, but taking into account this is 630 meters; then 
this antenna is ( almost ) on the ground as far as wave length is concerned..
Seeing how it performs on receive... " IF " I ever get on 630 meters, my plans 
are to load the short leg of the Windom, and use it in dipole configuration..
40' AGL will be about the highest it will ever get.. I'm interested in anyones
thoughts, and comments on how this antenna is really acting..
