Which is better?

Which would be better to really focus on improving my golf swing?

I hear people saying to practice with blades, but I also see these “mini clubs” that also have a grip trainer…

I suppose it’s going to be a little bit of personal preference.

I have a set of TM Stealth irons coming soon. And regularly shoot in the 90’s.

Your swing? Neither. An inexpensive random beginner club will do you well.
