I know you have questions about this ink and what mops to use.... I used the big Squeeze. Draw your own conclusions from that.
First of all, shake it well. These inks travel a long way to get to us and the pigment does settle. In use I found the ink to be a bit on the thick side. You will have to really squeeze it to get it to drip if you are using it right out of the bottle. This is actually good because you could probably squeeze a few more ounces of mop paint out of it by thinning this with alcohol. I haven't tried this yet but it definitely smells like it is alcohol based so the principle is sound. I would recommend using denatured alcohol, not Isopropyl (rubbing alcohol) in the mix. The reason is that Isypropyl has a high water content. I'm not positive but I think the water will make the ink gummy. So just use denatured alcohol from the hardware store and you will be good.
Before you start asking, I just made up these names....Anyways, I was able to get pretty clean lines from it but I definitley had to squeeze firmly. Some peeps might just take out the regulator, but if i were you I would just thin it a bit and get more use out of the ink. The regulator is there for a reason. Just ask your homie with the big silver stain on his jeans
Here is a close up. I think the 400 is a good value product. The Smash Silver is iller but this will definietly get the job done. Reccomended.
