This just may be the ultimate, as I'm not sure how it can get any better than this.
This is even better for me than the blue foam.
The blue foam actually works very well, but you have to get the right density.
Not enough material and it will leak, too much and it doesn't wick as well.
Using this method I can now stop worrying about what MIGHT be in the blue foam.
