Funny thing is, I'm from Minneapolis originally, and travel there once or twice a year. So this bike has definitely NOT been there for the last time!

The only thing that's a pain is when it comes time to put the wheel back on, the reaction arm flops around a bit while lining the axle into the front dropouts. A technique is quickly developed, but I'd recommend practising a few times when you're not in a hurry. (My first time was in the rain, with two whiny kids in the trailer yelling for me to hurry up!).

So, just a bit more hassle than the v-brakes.
That actually sounds like less hassle than V-brakes with a big, high-pressure tire (Big Apple or the BMX tires I'm using), where the procedure is:
1. Disconnect brake QR.
2. Deflate tire to 30-40 psi so it can fit between the brake pads.
3. Loosen QR and remove wheel, working it back and forth a few times to get it past the pads.

Disc brakes are the ideal, of course:
1. Loosen QR and remove wheel.

I doubt I'll be upgrading to a front disc though, but not for lack of research and interest. My understanding is that the Swift's stock fork uses a 1 1/8" threaded headset, with a steerer diameter of 1" above the headset to allow for a 1" I.D. riser. So the ideal replacement fork would also have a 1 1/8" steerer, probably threadless (headset upgrade) and require a new 1 1/8" riser like the Airnimal or Rans ones mentioned earlier in this thread. There only steel 20" forks out there with disc mounts and 1 1/8" steerers that I can find are mod trials forks with 365-370mm A-C. Wayyy too long. The only ones I can find with the right A-C length and offset are aluminum with 1" steerers. I suppose I could make this work with a reduction headset like the Chris King Devolution, but I'm wary of the use of aluminum in a fork and I'm guessing I'd give up a LOT in terms of ride quality. One other option would be a custom fork, but that's nearly $300 plus a new headset.

So basically, if I decide I can't live with a front V-brake the path of least resistance is overwhelmingly the drum route. Should be less than $200 to have a drum wheel built up.
