Ok guys I'm looking for a second opinion. A local friend who got me interested in concentrates swears by keeping his glass separate. He states that running combustion in a oil rig can leave impurities/residue that can hurt the flavor and overall oil experience. Is there any truth to this, and if there is would connecting to a vape be that same? I'm would assume not since vaping have so combustion. Just wanted someone elses opinion. I've got a budget for some new glass, but also looking to get into concentrates, should I be looking into one really nice piece of glass of 2x decent one. Keep in mind I would be removing the nail and dome and replacing with slide and likely cleaning H2O used between sessions.
