ESPO plus 1" springs

So i just pulled the trigger on a set of springs from ESPO for my 69 Barracuda, about a 3 month lead time and then the joy of paying the same agin for shipping and UK taxes! I did try looking for someone in the UK who could build a set of springs, but didnt really have much luck. Anyway if I'm going to replace the springs, I will probably also replace the shock absorbers. Given that a lot of folks on here have used +1" springs from ESPO any thoughts on good quality replacements. I'm setting this up for purely street and long distance driving so comfort and handling over pure performance. Thanks.
I went through a bunch of different leaf springs on the rear of my '70 E-Body in search of a spring that rode well and could handle the additional power I added over the years before finding the ESPO +2's. The ride quality is second to none, they didn't raise the car too much, and when combined with a set of properly adjusted slapper bars, they hook up very well. Those are 28 inch tall 325/50-15's on the back.
