On my holiday style operations I use a doublet with 300 Ohm twin lead cable.
The end of that 300 Ohm feeder is connected to a 4:1 BALUN
The BALUN is hooked direct to the K3S / K3
With the internal ATU I can use that antenna from 10 to 80 with 100 Watts
For details have a look to http://www.dl2mdu.de/antenna/

I would disagree. Most high power commercial operations use non-resonant
mismatched antennas. Typically there is either a tuner at the antenna or open
wire is used.

If an antenna is showing a VSVR of 3:1, something about the situation
is wrong, and most likely it's -not- the antenna. Fix the problem … feed
the antenna power where it's resonant, assuming the antenna is actually
resonant on the amateur band of interest. Expecting a tuner to compensate
for a problem external to an antenna is unreasonable, IMO
