For a training ride there was enough gutta adhesion on the rim bed and on a pre-instaled spare to have no worries keeping in mind to not play full-on Crit racer.
It was what it was and we dealt with it as part of operational SOP.
Race wheels were/are safer as tubulars since a flat can be safely ridden out of the field and onto the verge to wait for support and a wheel change.

It's refreshing to see a question posed about hardware use that one is un-familiar with rather than a strongly worded "opinion" on hardware one has no experience using.

PS: "10 Speed" meant 2X5, gears didn't index, low was 42X21 and we trained on tubulars. Somehow we got along just fine..............
