I have been using ZeroNine foils in out Edge 1 for a few years and I am happy with the results.
In my opinion the shuttle cartridges are well worth the $25, and stick with the Nexgen series. The few times that I tried the 100yd foils the used side bound up at about 75-80 yds, right in the middle of a job. I stick with 50 yd lengths now. The white I sometimes had trouble when flood coating, so I switched back to Gerber for that one.
Not all colors match Gerber, so bear that in mind.
I keep 18 ZeroNine ribbons (most used colors)
& 31 Gerber colors (infrequently used)
I always use the FrogSkin clear on graphics on vehicles and sometimes on signs (esp south facing)
