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.
