Ah ok, I see. Yeah, you're right, they won't be identical. If you put them on one way, then next time put them in the same slots but the other way round the poundage will be slightly different. To be honest the difference is pretty small. I'd say it's not worth worrying about. Plus, it's actually a hell of a job to get them off and put them on anyway, so you end up leaving the springs in place (but "uncocking" the gripper so they don't stretch). Thus, practically speaking, they're always the same way round.
