The PTL's I got 3 yrs ago and the ones from this year all looked the same and burned the same With the 3 yr old PTL's getting the edge on the heat (they were still a blend 3 yrs ago)
I found ptl (a lig product) & lig green to be identical in appearance and performance this year, I'll pop on them again.
Just dumped a bag of the Green letter Hard/Soft blend into the stove last night (got down to about 17℉). Bought these 3 yrs ago, and they burned great.
