My argument for macroless surround 2 points.
2. theoretical reduction of leaking points
The more important point of the two is the second. When dealing with a macroline there are two possiple failure points at each end. One at the fitting and one with the macroline itself. Any player who has been around long enough has faced that little annoying hiss that has streamed from an improper macro. Whether it is due to a traded gun and the previous owner didnt know how to cut a macro... or just old fittings that tend to leak. By making the gun macroless, you are reducing the points in which air has to travel between one body to another. In the dmf, the gun's possible failure points are reduced by 25%
Both guns are subject to leaks at
where they differ:
top of HPR
2 macro fittings
2 macro line ends
The difference being that the fix for the dmf will be a simple oring replacement and the DMR requires total replacement, loctite or recut of macroline.
Again both style of guns, macro and macroless, are prone to leaking, if you just take a look at either forum, but in theory it should reduce it by 25%... so it's not really a pointless concept to integrate.
