I dont think either of those 2 have changed Emris, both are still great, just my vapor production has increased do to more air through the intake hole, if you dont like an airy draw though dont do it,,, if an airy draw is ok with you then its something you and others will like. You can go a size smaller then 1/16th if you want to,, just opening it up a tad will make a big difference, with the 1/16 it is like a direct draw almost which I havent been as fond of in the past but on this ERA I'm liking how easy it is now and I cant believe the difference it made in vapor production, opening it up really got me a lot more vapor easier without sucking on the thing like I had to do stock. Everyone is different on how they like there draw I believe so its a personal choice. Vapor production is clearly way more and thicker for me since opening it up a tad..
I drilled mine out as soon as I got it. Don't remember what size though, just know that it wasn't as large as 1/16" Good to hear I might just try opening it up a bit more. Thanks MWA!
