I have absoutley NO problem on the 50 mhz portion of the 6 mtr band.
At my field, out of 320+ members ther are only 4 who fly on 6 mtrs. And then, only myself and one other ham fly that often.
You might want to check at the field you fly at who else flys on 6, and then pick your channel accordingly. I have xmtrs on 03, 04, and 05. use 03 most of the time, 05 occasionlly04 rarely
Litteraly "own" the channel when I am at the field.
By my signature, you can tell where I fly at.
In closing, I woudl not worry about HT's giving you any problem.
(That's unless someone REALLY dislikes you.)
