Looking to find out about Roller rockers, these will be for a mild 440.

I only have experience of Jesel, T&D, etc from when in had my B1.

What brand do you guys run, recommend or ones to avoid.

Thinking of some these listed below, in no order of preference
a) 440 Source
b) Harland Sharp
c) Crane
d) Yella Terra

Cheers,
