I ship many resonator banjos in the US and worldwide. I think the packaging is more important than the case. Many of my banjos are in vintage cases that aren't as sturdy as what you mention. Make sure the banjo can not move in the case, pack craft paper or bubble wrap on top of the flange to secure the banjo. I ship my banjos without the bridge and add bubble wrap on top of the head so it does not move that way in the case too. Make sure the peghead does not move but limit the packing material to not be too tight there. I put foam in the bottom of the box before putting the case in, fill the box with packing material of your choice so the case does not move, put foam on top of the case. Hope this helps.

Not familiar with either case but I have purchased several banjos that were shipped to me through the years and am of the opinion it is more the way the banjo is packed inside a case rather than the particular case that it is in as long as case is a hard-shell case and in good condition on its own merit.

Here's a link to a video Warren Yates of Yates Banjos put out on how to pack a banjo. I've used his system several times with no problems.

I posted this to my BHO BLOG in 2013 - I know the price tag for shipping a banjo via USPS, and via UPS, has risen - perhaps significantly - but I "retired" from banjo repair work in 2006 or so . . . grade me on a curve here. . .

I agree. Overspending on the case is way off the point. SECURING the banjo inside the case, and the case inside the packing box, are the much more important (and successful) moves.

Damage comes mostly from the banjo moving around inside the case, and/or the case moving around inside the packing box.

I go wild stuffing every open space in the case with rolled up newspaper or cloth, and the like so the banjo is firmly cushioned and cannot move side to side or back to front if you shake the stuffed case and banjo HARD. The stuffing should immobilize the banjo, taking any and all stress/strain, without putting actual pressure on the weakest spots like the peghead (don't let the tuners rest on the bottom of the case!), the hand volute under the nut, the heel (all around it) and the neck joint with the pot/resonator which "usually" doesn't lay completely flat inside the case anyway. If there's space under the neck area of the resonator, stuff it. Additionally to keep the weight of the pot from "crushing/splitting" the resonator in case of a sharp blow or fall, I stuff the resonator with rolled up newspaper too. Remember to put paper stuff ON TOP of the peghead, fingerboard, head, tailpiece, etc. so the banjo won't move in the vertical direction.

I wrap the case in duct tape covering the latches so nothing can come unlatched in transit.

As said above use good cushioning in the bottom of the case (styrofoam peanuts are USELESS). I've used folded cardboard, wadded up heavy brown paper, thick styrofoam sheets/pads, etc. I used fold cardboard to brace the case against the sides of the packing box so the case CANNOT move inside the box. Pack the top very tightly so the tip of the case can't "Pendulum" back and forth. The guitar and banjo companies have custom designed corrugated "hats" that go over the tip of the case and fill out to each side to prevent rocking.

What you basically can't protect against is completely crushing by being run over, or being stabbed through and through by a fork lift's fork. But those aren't the common injuries.

Label your box with an excess of stickers and written warnings to keep it standing up properly with the pot weight at the bottom and the tip of the case at the top. THIS WAY UP and FRAGILE and DO NOT STACK are all helpful. The Post Office makes you pay a fee for their FRAGILE sticker (I pay for them!)

You can buy a used guitar or banjo box at most music stores. I offer them $5 for a clean unbroken one and they are usually happy to produce one. Guitar boxes are slightly larger and you have to stuff them a bit more, but that is actually a good added cushion for top and bottom.

I'll add two considerations:

Some have suggested shipping without the bridge. I have received a banjo or two in the mail with the bridge turned on its side and held flat against the head by slackened strings. On one occasion, upon opening the banjo I discovered that at some point the banjo must have been transported on its face, and the weight on the bridge (even though it was flat) caused divots in the head. This could have been avoided had the bridge been placed in the storage compartment.

You might also consider putting a non residue piece of tape over each resonator screw to keep them from coming loose and bouncing around the case. Or alternatively, packing around them tight enough so that if they do come unscrewed they have nowhere to go. Making sure the storage compartment is secured and has no room to be jostled open would also be prudent, but this would depend on how the case is designed.
