I'm also using the blue foam with straw, and at one point I THOUGHT I was tasting the foam. Turns out I had (mistakenly) swapped for a stock pre-fill cart and my spare (un-prepped/un-primed/un-cleaned, brand new) atty.
Also, on my foamed cart, I did get a little of the foam flavor when I sucked it dry yesterday. But when I say dry, I mean BONE DRY. That thing really does get every drop of liquid out of the cart.
Tip: Notching the straw to fit down into the V (on a 902 cart at least) probably made it possible to get all the liquid out. Be sure to do that!
The blue foam mod EASILY gets 2x the liquid into and out of a cart vs the stock poly fill. EASILY!
