First time smoking beef back ribs

Beef. Back. Ribs.
First time making these. Scored membrane but left it on. Rubbed with Worcestershire and heavy coat of KosmoQ Texas Beef. Smoked 250° with hickory/cherry for 4.5 hours. Though not much pullback on bones meat was probe tender and temping well over 200°. Let ribs rest covered in oven set to 150° for a bit over an hour. I thought they were very good. Not a ton of meat but with a side item it was enough. My son ended up putting some bbq sauce with his. My wife said next time she’d like to try them with a sauce as well.
