No-Show Carto Slotting

[Provangelist]

I figured this out today by complete accident, and it's one of those "Why didn't I think of this before?!" type things. I slotted a carto and filled my tank as normal last night, just before bed. I was quite tired, so I didn't really even think much of where I was slotting it, I just knew I needed a hole. I was looking at it today at work, and as it turns out, I cut the hole just perfectly low enough that the top edge of the bottom cap of my tank covers the hole, but it's not low enough that the o-ring is on it. So it still feeds perfectly, but you can't see that the carto has been modified. You just see bubbles come up from the bottom of the tank. With the o-ring on my Lil' Mama' tank just below the cut, there is absolutely no leakage. Has anybody else tried this?

I haven't tried this but I am getting a rotary tool in the near future. How are the lil' mama tanks by the way?
