I guess it would depend on my budget...which we all know is non existent....and what I was doin. If it was an all out race effort, I'd choose the lightest lifters I could find. To me though, the size of the roller and them being pressure fed is WAY more important than weight. I would want one with as big a roller as will fit....I THINK that's .850 and want them pressure fed. I'm talking of solid roller of course. Hydraulic rollers are a total waste of space, IMO.
