Personally, I don't see the point of drilling holes in the stock stems or buying other stems that deliver more air, or the domed screens in the solo. The draw is restricted by design, to get a higher concentration of vapor, which is fine by me. It's not that hard to draw if you just sort of sip it. If you want a bit more air, just raise the stem slightly as you draw. Others have their own opinion, which is their privelege, but my preference is low temps around 3 and pristine concentrated vapor. My only addition outside of what comes in the box was to buy some screens to reduce the amount of particulates. I already had a bong, which I would have added if i didnt have one. I dont think you will be disappointed.
