Re: So, Remo UX heads are thin.
There are quite a few areas other than just the heads where manufacturers try to economize or "cheapen" in the construction of their beginners and intermediate kits. From the basic wood used in the shells to the hardware they install on the drums.
Evans also has their economy heads that are seen on many less expensive kits. I believe they say something like "heads made by Evans", talk about coatings that chip.
