That was way too much lumbar support. While a lot of support takes the pressure off the tailbone, it puts pressure on the lower back so the trick I guess is to find the sweet spot.
Along my ride this morning I kept pulling out tubes until I was left with just the big one spread out flat, which seemed about right. I'll try to pick up a camping or a yoga mat tonight and fashion something about that thickness with a little curve like you suggested.
