Hey Ro,

I'm with you on the 'no talc powder' thing; I really don't think it's necessary.
I've had sticky tubes before, but it's not like they're super-glued to the rim tape or the inside of the tyre.
Maybe it's worse in warmer climates, I dunno.

Having too much talc around the place can make it harder to grip the tyre to get it on,
and have you ever tried to get ALL the talc off the tube to fix a flat?
Puncture glue is very temperamental, it won't stick to talc coz NOTHIN sticks to talc.

Also, I like to use very high pressures (~160psi), and when the tyre gets a little old and a bit stretched,
I get paranoid that the presence of talc will slightly increase the chances of the tyre blowing off the rim
