[TowerTalk] Current Baluns

[cqtestk4xs at aol.com]

The only antennas that would allow 300 degree rotation with a sidearm on my proposed tower in V31 were Moseley.  They do not come with  current baluns.  Owner suggested the standard coil of coax (six turns).  Best of all he suggested the current baluns "waste" power.  I've never been a fan of these and most of the better manufacturers (JK, M2, Optibeam for example) use current baluns on all their antennas.
So , I'm looking for recommendations on current baluns.  Best for the price, best performing...I'm going to be running legal power but in contest mode on SSB and CW, but no RTTY, so I don't really need a 5KW monster.  Your thoughts?
