Ok, you're 216 pounds.

Tell us about your wheel.

Number of spokes?
BRAND of spokes? (is there a mark on the heads?)
Double Butted Spokes? Straight gauge spokes? Gauge?
Drive Side break?
Have you ever dropped the chain into the spokes?

Your LBS should have the data of the build.

As KBentley57 suggested, go back to the shop that rebuilt the wheel and talk to them. Apparently as you stress the bike (200+ lbs), things like even spoke tension are more important.
