Double stack magnums

Depends on the actual gauge of the needles. The diameter of the individual needles. Stacked are usually a bit smaller than woven. But all needle makers are not complaint with all tube makers…
Trial and error from each manufacturer is the way to learn..
cant hurt to have extra tubes though –
just buy a box of 20 or 50
and you will be okay –
: )

the goal is to get a good ink flow out of the tube -sometimes you want more gap on the sides – sometimes you like it snug.
W/ disposables there is a lot more friction though – so just keep it in mind.
I like the hard blue tubes..
that plastic seems to be the best –
Kingpin has em
they have long nose – and are pretty solid plastic – almost brittle…
some tube makers have softer plastic that you just wanna bend the things –
i like it more slick and rigid for my tubes. close to metal as you can get – (for plastic)

A double stack magnum is a needle arrangement that consists of a bottom layer of needles lined up tightly in a row with a second stack of tightly lined needles on top of the first. The layers have different numbers of needles in them. Common double stack magnum sizes are 5, 7, 9, 11, and 15.
