ARRL DX, CQWPX, CQWW, ARRL Sweeps, and less frequently these days, CQ VHF, ARRL VHF's, and some others when I remember.
I'll never win but have fun. Primarily Search n Pounce and try religiously keeping to that method for some reason. Dont think I ever ran a frequency for more than 10 minutes before switching back. Barefoot so not easy to run, especially in ARRL DX and CQWW and almost impossible in CQWPX where everybody counts for points so there isnt a clear frequency anywhere for a low power run. Used to finish in the top 15 Lower Power, Unassisted category but age is catching up and so not as "spry" as I used to be. I did manage to finish 1st place in the USA for CQ WPX back in 2021, low power, unassisted, sub category Tribander/Wires, that was a surprise. Usually finish pretty well for Ohio or W8's or Great Lakes Div if ARRL with many 1st place finishes. Sadly not so much anymore, but havent tired of being a competitor.
