Bill,

How much space do you have?  I think a V would be fine for the USA.  Maybe a single full sized vertical would work just as well too.  If you could put up two  then you could could phase them for endfire and broadside which would work pretty well for coverage to EU and the USA.

NE and NW are your two most desired direction.  I guess you Should move the house and garage  LOL.

I think any of the options will work pretty well from V31.  Are you planning on some RCV antennas?

Where in V31 are you building?

I've pretty well figured out what I will be doing on 40-6 meters.  However, 80 is still 
undecided.  Shunt feeding the tower is not going to work since I have all kinds of 
rotating antennas up the side of the tower.  So, I'm left with three solutions.
Since the last guy point is at 96 ft I could have two inverted Vees apexed at 96 
feet down to around 60 ft on the ends, at right angles to each other.  That 
would give me the ability to switch directions and gain/lose around 5-10 db.
Second choice is to have a full size wire vertical with 60 full sized radials 
over average ground.
Third choice is more complex-  a wire 4 square but...although the SE and SW facing 
verticals would be pretty close to having a good radial system The NE facing one is pretty 
limited due to lot lines and the location of the house/garage and the NW facing antenna is 
even more limited by the same constraints.  This one has a driveway in the way.  
Most of the decent sized radials would be pointing away from the direction the NE and NW are 
facing and the others would be fairly short.
Of course laying down the radials for the 4 square is quite a chore and I would hate to go 
through all that work to come up with crappy system.  Easiest of course, would be the 
inverted Vees.  I've used this system in the past and it performed quite well.  I'm 
concerned the lack of similar radial systems would ruin the F/B and gain and the compromised 
radial system of two of the antennas would also be an issue.
Your thoughts?

Location of the station is V31 and interest is contesting and DXing
