'Tis good to try out the new gizmos, toys, and delivery systems. The key, for me, is to try to do so carefully.
As equipment evolves, it's completely natural to try to improve upon what you have, even if it appears that everything is working well. (After all, those incandescent light bulbs work perfectly well, but now we have LEDs, energy efficient mini florescent bulbs, and more.)
Couple of drippers, couple of attys, some clearos, evods, tanks. The temptation is to load up on supplies. As soon as you do, or as soon as you take the plunge on that new APV or Mod, something 'new and improved' tend to come out.
I predict, with the way things are going, that several different new and improved juice delivery systems are just around the corner. Somebody is probably working on them right now.
