I think the original torque thrust (now repoped BY AR) had straight spokes with rounded front side of the spokes. They changed the design to TTD (disc) to the curved spokes to clear corvette disc brakes, in the sixties.
The pointed spokes are T-70 I think, and the vintage ones are expensive. The T70R, with the ribs on the sides of the spokes are REALLY rare, and really expensive!
The T70R were repoped a few years ago (for about twenty minutes) and I'm sorry to say I didn't get any. They are my favorite wheel of all time.
