Tough tittie?

Pardon the expression...I am getting better at my egging.  But I did chicken breasts tonight, and pulled them as I passed 160 IT.  They seemed tough, not dry, but tough.  Could it just be the chicken?  They were boneless/skinless breasts with rib meat attached.  I had a heck of a time getting them to temp.  I was doing Kristie's Roasted Cauliflower in Gruyere Sauce along with grilled asparagus.  The Cauliflower was excellent, as was the asparagus (except for a few ends that were stringy) and had a great crunch and flavor.  The flavor of the chicken was great as was the moisture, but they just appeared tough.  However, compared to hundreds of previous gasser cooks, these were perfect!  But the first chicken breasts I did were moist, tender, and even good as leftovers.  I don't know about these...

For bone in chicken breasts, I usually go to 155. Tender, juicy and flavorful. Not sure what a 'boneless with rib meat attached is'. I thought rib meat attached referred to bone in.

I suspect it is the meat you are starting with. For example, Publix offers their normal chicken breasts, and at a third of the cost more, they offer the "Greenwise" chicken breasts. Comparatively, there is a huge difference in texture and flavor between the two. As with most things, you get what you pay for, but there are a lot of variables.
