[TowerTalk] Choice of antennas

[yo3ctk]

I'm in the process of building a medium performance station dedicated to contesting. Transceiver and amplifier already purchased (MP V Field and AL-800H), in process of acquiring a 24 m (78 ft) tower with an antenna load capability of 1.30 sqm (14 sq ft) @ 160km/h (100 mph). I would like to ask for your collectve wisdom as to the best choice of new, modern antenna(s) for the setup above, with following criteria:
 
1. Coverage: 10-40 m (80 and 160 will be covered by wires and/or verticals). Not interested in WARC bands.
2. Performance: min. 3 real el/band (2 el/band for 40 m). Single antenna preferred. 
3. Size: According to tower capabilities. Max. boom length 10 m (30 ft)
4. Best weather survivability with min. maintenance and easy install
5. Price: although not the limiting factor, reasonable priced
 
As far as I can see, the only real contenders may be Force 12 C4XL or SXL or Cushcraft X9 or X7 combined with an XM240.
 
Any other ideas, anyone? To which one your preference would go? Thanks,
