At 220 pounds, my first thought was 36-spoke Deep V with a Tiagra rear hub. Tiagra is effectively 105 with a Tiagra logo, great value.
If you're looking for a wider rim than the Deep V, but aren't ready for a 650-gram Chukker, there's always the Dyad at about 480 grams. It's a popular tandem & touring rim. But I think the Deep V would be a better pick if you're using tires in the 23-28mm range, and they're still pretty stiff.
In any case, ask around at the bike clubs to find a reputable local wheelbuilder. After you've had about a month on the wheel, take it in to the original builder for a check-up.
