Ideas for Add-ons

This is my 14 year old’s set. We recently upgraded from a beginner set (ddrum d2) to a Mapex Meridian. He loves the set and has been putting it to great use so far.

He’s already mentioned a few things he would like upgrade or add on (an 18” medium thin A and a china crash of some sort) and also a better throne.

I’m just really looking for some more ideas of things that we could surprise him with that he hasn’t mentioned yet.
