Money vs Horsepower

Crane Golds don't like big spring pressures........one vote for solid.
I'd give serious thought to a hyd. roller.
They are doing good things with them recently.
You're buying springs and pushrods for any of them.........maybe not the solid , but I would.
Hyd. roller will cost somewhere in between a solid and solid roller , but the put them away wet aspect is a big plus.
