I don't know what the screens are for.
I put the plastic cap on the stem after threading the stem through the other loop...kind of like the caps on a straw...I think that's how it was designed, but I don't know.
It's solid feeling like the DV and the Solo.
silver420surfer...you will get your solo comparisons here. I will comment once I have hit it enough and found the sweet spot. The draw is not wide open, but very open...more than you need. So while the Solo is physically restricted, this one will be functionally restricted, which I prefer. So far, I like the feel better and it is easier to hit...now we gotta see if it fogs like the Solo.
