Topband: Inv Vee or Inv L

[smislo@swipnet.se (Samir Popaja, 7S7V / SM7VZX)]

Heloo,

I would like to put some antenna for CQ 160m contest. The antenna
will be on 25m high building, 25m wide and 80m long, north/ south direction.

What's better for cq160m contest?

Inv Vee on 10m high mast on the building 25m high, 20mx80m or
Inv L on same building with 10m vertical part + 30m wire to the building,
with 4 L/4 radials
or couple more.

Thanks
