Topband: Transmitting antenna

[allan1 at dejazzd.com]

I have a graasy flat area at my home which is about 175'in length and I want to put up the best XMTG antenna that I can. I will also receive on it using my TS-850SAT 
 There are lots of trees (about 50' high) on both sides. If I put up a dipole (assuming that is best) should I have both sides bend down equally or should I go for one leg straight and the other bent down further

Any help would be greatly appreciated
