Finally, a setup I can live with: 510 carto + 901 cart

[h8isgr8]

I know other have done this already, but this is the combination that finally makes me feel like I've found what I've been looking for.

It combines all of the things I like - 510 compatibility, whistle tip, great flavor, easy refilling, longevity dripping doesn't provide, etc.

What more can I say; I'm lovin' it!

Or you could just go with V4L batts and cartos.

I just purchased 901 whistle tip carts--$2.95 for 5. They ARE great on a 510... shorter, better wading matl. It's a better 510 experience. I also trim them and use them on 808d-1 cartos.
