Poll, go polyglass or stay radial!

My Duster 340 is restored totally stock. i have had BF Goodrich T/A radials on it for the last 18 years, there getting old! ..lol Should I get new radials or go with the Polyglass tires. I know the ride would suffer a bit but i only drive it about 250 miles a year...

Goodyear Polyglass E70 14
or
BF Goodrich T/A 205 and 215 70's
