It's a jungle, or a minefield, out there.  A whole lotta snake oil 
being peddled.  OTOH, you'll find a lot of good reading at

That's plenty of room.

That's not too bad.  Plenty of hams (including me) have made DXCC 
with wire antennas that high.  Mine is a doublet (a wire fed at its 
center with 600-ohm ladder line), overall length = 30 meters, of 
which the middle 20 meters is horizontal and 5 meters hangs 
vertically at each end.  If you're interested I'll email you plots of 
its radiation pattern for all bands 80 through 10 meters.

Balanced antennas with balanced feedlines are best for HF, IMO. 
Since those tuners are unbalanced, you'll also need a balun.  I'd 
recommend a 4:1 current balun.  Putting up as much wire as you can is 
OK up to a point.  I wouldn't make a straight doublet longer than 
1.25 wavelengths, though, to avoid putting deep nulls in its pattern. 
However, the trick of dropping about 5 meters vertically at each end 
(as I have) can fill in the nulls.
