C70 + Heico springs

Hi guys, I’m currently thinking about throwing out my H&R coilover suspension and “only” Heico springs (-30mm) up. Will I upgrade to 19″ Tomason in the spring. Now my question. How do the springs behave in terms of comfort? That it gets tighter is clear to me, but is there any unpleasant abnormalities? Does someone have the Heico springs in it and 19″er on it? Would I be happy about photos! All C70 that I’ve seen with feathers up to now have disappointed me a bit, because they were a bit deeper than in the back, from which photos would be really top! Thank you already in advance!
