Looking for Vest Pattern (knit in the round)

Does anyone have a favourite online pattern for a pullover vest, knit in the round, in sizes suitable for the upcoming campaign, using a worsted/heavy worsted yarn? I've been looking online a bit but haven't found anything that really takes my fancy, so I thought I would poll the collected wisdom of the KAL/CAL.

thanks!

PS Just finished a first pair of mitts for this campaign this morning! (well... except for one thumb. :).
