ND2 ST with BF roll bar - which Progressive spring better

[JeffreyK764]

Looking for a good match spring with the ND2 stock Bilstein shocks. as the Blackbird Fabworks roll bar adds about 26lbs. and the RF weights about 44 lbs (mostly rear weight) more than soft top, which Progressive springs, RF or ST, would be better matched for the rear/mid weight increase from the roll bar?

Thanks for any input.

For me....the love combo is Bilsteins and our RoadsterSport Springs.
