A suggestion that isn't the tire you should ride but one that might stop a few thorns from even getting started. Tiresavers. Small wire and plastic tube thingies you attach at the brake bolts that ride on the tire and knock objects off as the tire rolls past. There have been at least one recent thread re: them. I think they are still made and if not, they are still out there, plus you can make your own with coathanger and tube from a hardware store. Not ideal. You here them and they spray the bike in front of them with road dust, but they can stop a lot of flats, Many of used them back in the days of sew-ups. (I'd wear through the wire and rebuild them with coathanger.)
I'll go look for those posts and come back if I find them.

Edit: Well that was easy? Typed in "tiresaver" and first post:
Now I would bend the wire over the tire a little more so it fit the tire better.
