I've been using mine with the pellet fuel from my pellet bbq, not the same... I would recommend buying 100% flavour wood pellets for it...
you find there is a difference?
i personally dont find its enough of a difference to buy the flavour packets although i do like the flavour of oak so maybe thats why.
That's right! If your burning oak fuel and throwing it in the tube your all set!
I have tried multiple times to go hard on hickory, used the fuel in the tube and found it diluted the flavours a bit more... I dunno..
All I can say is, when I used flavour wood in the tube, it tastes way stronger... But yeah as you say, if you like oak, stick to the fuel pellets no worries!
