4-link rear: Coil springs or air shocks?

[SpareParts]

I vote coils too.... I'm going to change from the progressive rate to a linear rate. The progressive rate is too soft at the top for me, 3" of up travel, they let me bottom out too quickly with a little extra weight.

That is close with the ruffstuff truss, might fab my own. Good call on the progressive rate coils, I was wondering with how soft the tops usually are on those.
