I have a wood stem from Ed and used a couple of times over the last 2 years.
I bought it because I broke stems weekly. While I was waiting for more glass to arrive from CANADA I got the Wood stem to keep medicating.
It's very pretty and got me through a difficult time. However now I have lots of glass. The flavor is so pure and I like the "ORGANIC" flavor of the CANNABIS strain I'm medicating with. Glass does not interfere with the flavor profile as wood does.
Wood is more durable for sure.
Glass is more fragile no doult.
If durablity is your priority go with Wood!
If Flavor is your priority go with Glass.
Like I have said before we all have different priorities.
ORGANIC flavor comes from CANNABIS not the device accessories!
If restriction is your issue then why don't you have a PHVES? I have both because depending on the cure of the flower determines if I use the STOCK or PHVES version?
