I keep most of my gear. I have two full kits ( stave & ply) with stands and cases and a selection of snares and cymbals. A good kit is a a good kit and doesn’t really go out of style provided you don’t go for overly deep or shallow sizes or unusual colour. However, like many of us I traded up to this situation over 10 years and then stabilised to this. I also have space in the house to store everything without getting in the way of domestic life.
