What balun, homebrew or commercial, if any, should I use? I almost always run 5 watts, all CW.
k9yc.com/RFI-Ham.pdf Since you're running QRP, a single 2.4-in o.d. #31 core is all you need. Study the data in Appendix One for small diameter wire, and wind the number of turns of your coax through it that puts the impedance peak in the frequency range where you want to operate.
