I'm not sure what you mean by 'greater precision'. The current system uses a two hole 1/4" punch which offers large holes. The supplied negative carrier has the 1/4" brass pins already spaced. Once you've taped the film leader to the original negative, and punched the masking film, you get perfect registration (or as perfect as it needs to be) every time.As I have previously mentioned my system is enlarger mfg and model specific. I purchased Lynn Radeka's original system and looked at Lynn's new system and opted to spend the additional money because of greater precision.
The negative carrier slides into the mount, and is held in place by a magnet, again offering perfect replacement. You can remove the negative carrier, replace it, etc. and it always goes back to the same place.
Am I missing something?
