I have two DFs and am down to a single recumbent which of course I put most of the longer miles on. I did find that riding my road bike this weekend it was a nice change of pace and allowed me to ride with some social upright riders a little better. I also am still hanging onto my fast road bike for when I want to fly through traffic at the 2499/407 nightmare with four corners shopping and lots of construction. Curb hopping, looking over cars and suvs to make a turn and really quick tight turns are required if you want to get through there in a reasonable time. I find it perfectly safe to do it on my hurricane it just takes more time and waiting for bigger openings and such. That and the fact that if my road bike gets damaged or stolen I'm just out a junker

Something to consider, how many miles is many miles (and will you be doing them all at once - unsupported)?  The reason why I ask, when Shellene and I were looking at bikes we limited ourselves to bikes that use the same size wheel, this way we only had to carry a spares kit (2 tubes, 1 tire) for one size, not two.

I read that also and it makes sense with what I've observed. I ran a Jet60 on the front Corsa for about 9 months and there wasn't much of a difference compared to the stock rim in crosswinds but a big improvement in speed. Then I put a HED3 on the front (was running one on the rear) and while crosswinds are more of an issue, speeds are even greater and there have been a few times where the sail effect of the front HED3 was obvious. Heading up to Waco last week I was going uphill slightly when the access road curved around and my speed jumped up until the road straightened back up and I lost the wind thrust (from the crosswind), so the HED3 isn't coming off anytime soon if I have anything to say about it. Was pretty cool going uphill at 27mph against a crosswind on ~40 lbs of bike and gear and barely cranking. When I put the HED3 on the rear early last summer the bike really stabilized overall but I think that was mainly due to the wheel flexing less. It's an old HED3 so my next rear wheel might be a disc.

Thanks for saying that. Almost every time I told someone that the wind lifted the rear wheel of my Corsa up off the ground when I had the coroplast panniers mounted I had the feeling they didn't believe me, though it was a little hard for me to believe since I was packing about 25 lbs of gear on the rear of the Corsa when it happened both times. It was a weird effect as the bike didn't really go unstable. The rear end just up and moved over and I kicked out of the left cleat to stabilize, more out of instinct than need, I suspect.

Mark, do you still ride the xtracycle?

Not so much the weight of the second tube, that's what I normally carry on my 'bent now, but the weight/space of a complete second set if I was running mismatched tires.
 
Although Nelson pointed out that he never had any issues with his 20" in the front, I would probably never ride without a spare tire for each wheel if I was running mismatched wheel sizes (or a single spare tire for both wheels if they are the same on long rides - I learned that lesson the hard way).

I've had a 20" tire go, but with every flat I've had, I think a boot would have been fine and no spare tire needed.  I've always carried one on brevets, but I think I'm going to stop and carry a boot instead.

well, even if you end up changing your mind and wanting something later on, bents hold a decent resale value.  If I were going to buy a sun, that would have been the only model I would have bothered with.  I think you'll end up enjoying it until the next round of bike lust takes over.
 
So where you coming over for a ride?
