For the 902, I'm using the RSP mod but using Blue Foam as the plug, instead of the scotch-brite suggested in the OP. I also use a grocery-store drinking straw, instead of coffee stirrers as posted in other foam/straw mods. The foam creates a small vacuum in the drinking straw to remove all the liquid from the bottom of the cart. ALL OF IT...and since the drinking straw itself is roughly the diameter of the inside of the cart, there's very little left around the inner cart that doesn't succumb to this vacuum and move into the foam. (just my theory, but seems accurate).
It's also VERY important to wash the foam with hot water first. (no soap necessary, just really hot water). That solved 90% of my residual foam flavor problems.
How to: MV 902 RSP (Reservoir Straw Plug) with Blue Foam Plug
Done properly this WILL wick until the cart is dry. I've been doing it for over two weeks (since my first day vaping), and have not had ONE cart that tasted bad that wasn't bone dry. Bad taste = empty cart OR unwashed foam. It's that simple. And the cart itself will empty before the foam goes completely dry. I've even done my own version of "dripping" by just placing 2-3 drops on the foam plug, reinserting the cart, and vaping from there. If it doesn't seem to wick quite as well at first, make sure the foam is nearly saturated by lightly pushing on it with tweezers, or cut a tiny bit off to make it smaller and reinsert. It doesn't have to be exact, but should be snug enough that it takes a slight tug with tweezers to fully remove from the cart.
You can simply rinse off the foam if you're changing flavors in the cart, but the foam is reusable. And the juice won't leak from the cart. I keep a few un-capped filled carts in my pcc with this method, and they don't spill a drop, even with the PCC in my pants pocket.
Anytime I get leaks/fluid in the mouth with this method, it's because I put too much juice in the cart. All leaks are after vaping it over-filled, and don't happen until I either remove the cart to check it, or I take the mouthpiece off the cart to look for excess juice (the condensation on the cart/in the mouthpiece squishes out on re-insertion. This happens anyway after vaping on a 902, and the cart and mouthpiece should always be wiped down before refilling to avoid residual flavors).

How to: MV 902 RSP (Reservoir Straw Plug) with Blue Foam Plug
Needs:
- MarineLand Rite-Size "U" Foam Aquarium Filters (search the forums, these are well-documented)
- Regular grocery-store drinking straw (fast-food straws are usually too big)
- Scissors
- Tweezers
Steps:
(Figure 1)
(Figure 1)
- Put straw down into the cart, use a pair of scissors to cut it off along the top of the cart. Take the cut straw out, cut a pair of small 2-3mm tall "v" notches on either side of the bottom (Fig. 1, Fig. 2)
.
Re-insert into the cart, aligning the v-notches to slide down over the crossbar in the cart. It should leave roughly 3mm open space above it in the cart. (Fig 3.)
- Fill the cart with juice up to the top of the straw. Should be 19-20 drops.
- Cut a piece of blue foam about 3mm x 5mm. See Fig. 1 (Easy way to ballpark is foam width is about the same size as the cart the wide way, length is just over 1/2 the length of the inner cart without mouthpiece.). Roll it up the long way, compressed a bit, and insert it into the top of the cart. Don't insert into the straw, just squash it into the top of the cart above the straw. (Fig. 4)
I use a pair of tweezers to help here. You want to make it flush with the cart top, and using the tweezers, compress it in until the foam starts wicking fluid, then allow it to expand back to flush with the cart top. - (Optional) Sometimes during refilling, I will also take the step of using a q-tip or napkin to soak some leftover juice off my atty. For normal cleaning, I put on my manual battery, and run the atty 8 cycles of 8secs each until its semi-dry.
- Insert cart into atty, and enjoy!

I will give that a try in the am and see if it will work as good for me as it does for you. I have been using the PTB and the blue foam. The PTB seems to work better for me but I will most certainly give this one a shot! Take Care
