I use the primos soft case as well for my XT. Works great. If you want a hardside case, the rectangular SKB is awesome, just stay away from the "Freedom" case that is a lot less money. They are hardside, however are not airline approved and also we had 5 of them in a row show up at the shop cracked in shipment. If they are cracking in shipment to our shop, what is going to happen to them on an airline?
