Won’t be common on this (Titleist user) web site of enthusiasts. Typical mixed set would be 5-P T100s and T200 or U500 as driving irons. The lofts match up.

So mixing hybrids or driving irons with iron sets from different vendors would not be uncommon. Even if someone here volunteers a combination, whatever they use may not be the best combo for you. Just will take you time to try various components to see what works best for you. ….If you found something better than Titleist.

I game a combo setup but its all Titleist !!!! I couldn't imagine ever mixing brands in a combo of irons (heck, or switching from Titleist either LOL).
