id say a regular barrel. you dont wanna drag around all that extra weight which prolly wont benefit you that much for callin in yotes. most of my shots are somewhat quick. i recomend short and light. i have the vlsf which has a 22inch flutted barrel and i love it. but for varmints you might like a heavy barrel better. what kind of varmints? my hunting partner has the sps and he really likes it. a little heavy for me to be lugging around for a few miles.
