I am a stick burner and take pride in my smoke ring, But I have to agree with Bear. Here is an article from a friend of mine who has a PHD in Physics and a BBQ enthusiast .This IS HIS EXPLANATION
Even though yours is a Gen #2 MES, you could get better smoke flavor by using an AMNPS.
As for the Smoke Ring----You don't get them in an electric smoker, but they are all show anyway.

Summary of the mechanisms leading to smoke ring depth and profile:
- Smoke rings record the environment in which they are formed
- They are generated as carbon monoxide or nitric oxide combustion products diffuse into the meat,
- Turning myoglobin pink.
- Smoke rings grow more slowly over time.
- And the ring only stops growing when the myoglobin is deactivated, at ~170F on the surface.
- By analogy with photography, nitric oxide is the developer revealing the image, and heat is the fixer, stabilizing the image
- In humid smokers, cooking cold moist meat low and slow, wide wedge-profile rings occur
- When cooked fast in smokers with lots of airflow, dark narrow wall-profile smoke rings occur
- Smoke rings do not add much flavor, but indicate a smoke fire was used...
- Nitrogen is a minor element of fossil fuels
- During combustion, nitrogen compounds present in wood burns, and are mostly transformed into nitric oxide (NO)
- But only in a hot fire, with plenty of oxygen
- Even though there is 100x more carbon monoxide than nitric oxide in smoke, most smoke rings are NO-based
- NO is a small and mobile molecule that passes from the smoke through the meat's surface
- Inside the meat, NO bonds more strongly to myoglobin than oxygen or CO, producing a nearly permanent pink color
- Surface water on the meat is not required to synthesize nitric acid intermediaries, or to produce a smoke ring, but humidity helps
- The smoke ring stops growing when the myoglobin molecule falls apart (around 160F)
- Carbon monoxide is the most common wood combustion product
- It is a small and mobile molecule that passes out of the smoke and diffuses beyond the meat's surface
- Inside the meat, CO bonds more strongly to myoglobin than oxygen, producing a neon-pink color
- This pink color is stable for days or weeks in the absence of oxygen, but fades in minutes when exposed to air
- The smoke ring stops growing when the myoglobin molecule falls apart at the meat surface (around ~160F)
- While wood is 50% carbon and only ~0.2% nitrogen, nitrogen oxides are ultimately responsible for the persistent smoke ring
- CO, in the wrong place at the wrong time can kill
Lipstick on a pig, so to speak.
