Best Hammer/ Dolly Set advice from a Pro Panel Beater

I'm not much help. Most of my stuff is snap-on. I did get a screaming deal on a Mac set at a secondhand store. I like the Mac dollies but I rarely use the hammers. I really dislike fiberglass handles, not that these Mac tools are fiberglass. Too much shock from the glass handles.
My advise is to buy good hammers. Dolly's can be just about anything. If you are looking at metal finishing, then that would require some fine dolly's. I have like 15 different body hammers and use the same 2 90% of the time. The same can be said for the dollie's. One of my favorite hammers is a Proto. Practice is the main thing.
