Finally got around to using the bear mountain pellets today. Did some veggies for salsa and some chickens for pulled chicken. I used the applewood pellets. Ran them at 225 for about an hour, then 245 for 3 hours and then raised temp to 265 for the last hour. Appearance wise, the apple pellets are a bit darker than Weber's and are a bit "fatter". I didn't have any issues with jamming (on latest firmware and have all upgrades / fixes in place).
No complaints on the flavor. I will say that the pellets produced a ton of ash. My ash pan was full after the cook (it had 5 hours of ash in it before starting from my last batch of ribs) and the outside of the smoker had considerable ash on it.
