As a random triathlete, I have a lot of opinions. Even about things I don’t know or care about. Yesterday, I got in a fight...

    I covet the bike-tube-shelf you have in your living room.

    Seriously though, latex or butyl?

    @James Lange Oh, seriously? Seriously, butyl; latex for tubulars. Bam, problem solved.

    @James Lange If you want data: http://www.bicyclerollingresistance.com/road-bike-reviews/continental-grand-prix-4000s-ii-latex-tube-2014

    If you want pure speed, latex inner tubes are definitely worth the trouble. When making a correction for an average road bike speed of 23 mph / 36 km/h and a tire pressure of 120 psi, a pair of latex inner tubes have 4 watts less rolling resistance. If you like to run lower pressures, you will save close to 5 watts at 80 psi.
    If I'm going to the all the expense of having a nice pair of race wheels, I'm going to install the fastest tires and tubes I can find. That would be latex. I can't think of any reason to not use latex tubes in your race wheels. Unless you are in my AG.

    @balsdorf @James Lange I almost said: butyl for training, latex for racing. But I didn't want to get all into how it depends on how you store them and on how long the race is and on proper installation, etc, etc, etc. Because then I started to bore myself.

    Latex for both being faster and less prone to punctures and pinch flats. Basically, they're better in almost every way.
