I'm changing pins over in a 2nd hand pair of flats, except it would seem quite a few of the traditional top-hex-bolt-head type don't want to budge and have rounded off. (always thought this was a bit of a design fail)
Anyone got any brainwaves on the best way to get the little buggers out before I start getting busy with the hacksaw?
To clarify the pin type:

Mole grip very tight on the sticky outy bits.
My surgeon had to use them on the bolts in my hip when he rounded a couple off trying to get them out, so they're not always the wrong tool for the job...
Drill em out
set of large pliers or mole grips.
Penetrating fluid, or get a hacksaw and cut a slot in the top to take a screwdriver.
mole grips
OK. Molgrips out, hacksaw primed.
Cheers!
Two down, one stubborn git to go.
Then it's onto pedal number two.

They do have thru pins too, which are good.
TDH, I think these are the way forward:

Good luck PMJ.
The best ones I've found are the thru pins. I've just changed mine on my superstar nano's and it was stupidly easy. On the straitlines there's a few that are bashed and hard to get out.
