I like Ed's stems, but I find that they get my Solo hot, and I get hot vapor, I don't like hot vapor. With the 2014 models, the original glass stem is the best. With my 2013, the PVHES STEM worked better, but not so with the 2014 version.
I couldn't agree more. Full points on all counts.
I like my new Ed's stem but it does run the battery down faster and make the top part of the vape hotter (I assume by conduction as well). If not careful the stem just outside the cap can burn my tender fingers rather than just 'feeling hot' as the glass does. Since I'm a sipper by nature, the extra heat (which I don't quite understand yet) isn't a big deal, although dropping down to 3 to try to counter it clobbers production.
My Ed's stem is also the largest in diameter of all my stems by a fair bit. I had to force it into my oldest Solo (loosest one) after filing off a couple burrs as it was. The burrs bothered me as they're sure to scar the seal but since others don't seem to have this problem I'll assume mine is a fluke. Neat thing all told, 5,400 year old wood is not an everyday thing for sure.
I fully agree with the new/old stock/PVHES thing as well. I run notched o-rings in my older ones which adds some more restriction, the PVHES seems to balance that out again. My 'using stems' for them are therefore PVHESs. The new one doesn't have a ring yet, but for now the PVHES is 'too open' for my taste.
FWIW I think the restriction on Ed's stem is about on par with the stock ones even though it has notches? What do the other owners think of that opinion? TIA
