Does compression straightening affect spine?

Well, good. Always good to have something to blame when I miss. (lol)
Strelets:
I use either ash or tulipwood (American poplar) for arrow shafts. I straighten them by heating over a gas flame and bending over the base of my thumb, then laying them on a flat surface while they cool. I have measured the stiffness before and after this process. It does not affect the spine, at least not within the limits of accuracy of measurement. And yes, you do have to mark the shaft so that you measure on the same axis each time.
TSA:
we use a compression straightener to do all of our shafts, but it has a concave surface that matches the diameter of the shaft- prevents any flat spots on the finished shaft.

Good idea. I'm not sure if it matters to flight, but if nothing else it would look a lot better.
Edit: By the way, is this Wayne or Neil? I'm about to place an order from you guys! :)
TSA:
hi
this is wayne ;D
Neil works for us as admin and order processing, the idea is to give me more time to design and build all the machinery this industry is so hungry for! (f) and keep the shop crew in good stead!
you can get a good roller straightener from ace broadheads, its all aluminum, and i find the groove a tad shallow, but its a very good little unit
one other project we have been working on is, commercializing our straightener,
we already make our own, with yew wood handles ( warmer and prettier), but need to make a bunch for inquiries we keep getting.
this may inspire me to finish up the parts for a batch ;D.
