Agreeing with Merlin and TG here. We have a 36H Aerohead in front and a 36H Deep-V in back with light high pressure tires. Love how the bike feels. We're a fairly aero team and when the road tips down a little we are just gone. When the other teams catch us, they're shouting "Hammerheads!" which is not true at all. It's not so noticeable under 25.
I've had very good experiences with Rolfs on my single and wouldn't hesitate to put them on our tandem except for the cost-benefit thing. Their rims wear just as fast as any other rim, maybe faster. We had a side-by-side coasting duel with a Speedster with Rolfs and a team about our height but heavier than we are. We beat them fairly handily.
