You're hitting on what I'm nervous about.

Do I add length to swim training...or break it up and try to swim faster?
Also, as far as the wheels, I'm still interested. I do a local omnium and some duathlons. I don't want to drop $1500 on wheels if a $500 used set will give me 90% of the upgrade advantage.

I hate how people are so damn critical on message boards. I know how to run, and have been successful biking but hate bike culture, which leads you to multisport....I figured things would be more positive.
