My daughters family had the strips tonight. They have a Recteq 590. The steaks were seasoned as I do with salt, pepper, onion powder, etc. Placed in smoker at 250 until approaching Medium rare, and were removed and then the temp elevated to high. They were then placed on reversed GrillGrates and seared. They came out Medium/rare with a nice seared surface. In addition, they cooked two of their own un-aged prime strips of the same size and thickness.
Report:
Aged strips were very moist but not as much as the prime strips(more marbled). Aged strips were more intense in flavor to them. The un-aged strips were more tender than the aged choice steaks. So we both agreed that aging did not have appreciable effect on tenderness that was provable.
Over all, while the flavor was bit more intense (I did not have that experience), there was not enough overall improvement to justify the work and cost of the process.
One more family trial will be done soon.
