34 spoke? Is that a typo for 32 or 36? Either way I assume that will be sufficient for a 230lb rider (I'm 227 nowadays, but rode for years on 32spoke wheels at 245-250 plus up to 30lb of baggage).
Gatorskin 25's seems like a good choice, personally I would bump that up to 28 if they fit. But only when the 25's wear out.
