The only difference seems to be single versus double eyelets. At your weight, I wouldn't be concerned at all with a 28 spoke, single eyelet rim for your do-it-all wheel. I'm in the same ballpark and commute on a 32 hole, single eyelet IRD Cadence VSR rim'd rear wheel. The Cadence rim is a 390 gm rim which is about as light as it gets for a single eyelet rim. I do have the benefit of the offset spoke bed evening out tension but I also carry an extra 5-15 lbs. over my rear wheel on my rack every day. I would recommend using a heavier spoke gauge on the drive side and lighter on the non-drive side to avoid overly slack non-drive side spokes during heavy use. I went with DT Competition drive side and DT Revolution non-drive side but you could go a little heavier with Champion drive, Comp non-drive.
