But, when my tubular wheels are flat (due to punctures) I use my clinchers till I get the tubulars repaired.

I've only had one blowout with a clincher and that happened immediately when I got on the track (like 20 meters). I suspect that was because the bead wasn't set right. It was a Conti GP 4000 tire rated for 120psi and I pumped it to 130psi. I didn't mount the tire myself, the mechanic at a shop did. I should have checked his work. I count that as user error on my part for not maintaining my equipment myself.
I did think that 120psi seemed pretty low... especially on a track rim (no heat from braking), also they are a solid looking rim and not exactly lightweight!

I think I am going to start running 145 in them.
