Hi, Steve.  Am using an UltraLight (forgive the spelling) Junior with 
a 4-1 balun.  Would try to make an RF choke out of the feedline, but 
barely have enough for a little bit of slack to account for wind.  No 
problems from about 3.8 up; it's below that where I have a 
problem.  Aside from that, everything from 3.8 or so and up seems to 
work fine.  Sure, I could probably get a tuner to get closer matches, 
but not sure if it's worth the money.--Matt, N1IBB.
