I use protechtor cases from specialty xl.
hard cases are the only option for me. If you've ever been on tour and seen what can happen to gear inside a trailer (driving across manhattan!! ahhhh!!!) I also have other people sometimes handling my drums and they do not respect them.
I really like the protechtor cases though, the bass drum case has built in wheels, and they are still rolling strong after 10 years. you have no idea what kind of abuse these cases have seen. I even dragged my kick half a mile over a gravel parking lot and the wheels are still fine.
I have some various humes and berg enduro cases, I really like their drum cases, I have a snare case that is 15 years old and has been all over the place with me.
I will say this, don't waste your money on padded hard cases, or lined hard cases. Just get an old tshirt and put it over the drum they will be fine. the foam always ends up breaking up or getting torn or snagged and then leaves sticky residue on everything.
I've used stagg cases on some rental kits and I was pretty impressed, although the handles are made of nylon webbing instead of a hard handle.
I'm in the market for a new trap case, my humes and berg enduro trap case with wheels is on it's last leg. a bunch of the screws have fallen out and rivets busted, but it still does the job and is still rolling.
PLEASE invest in a hard cymbal case! I have the protechtor rolling cymbal case, pretty awesome case. I had my cymbals fall out of a moving vehicle turning a corner at 20 mph and my cymbals survived!
