I recently bought a new, slightly smaller (20") spinner. I'm not sure I like the style I chose but I'm trying to like it. I loaned out my last two 21" bags to relatives and they like them so much I haven't reminded them that they were a loan. I still use my 30 year old Jandd backpack (edit: which opens completely like a suitcase) but my shoulder has been giving me some issues.
A couple of months ago I went looking for a new bag and let a gorgeous Samsonite hard side seduce me. It's a slightly bumpy textured, graphite colored 20" spinner. It has some external flat zippered pockets. It has a zippered divider inside. I tested it in the store by rolling it around, extending the handle several times, measuring the dimensions and lifting it with one finger. I thought I had a new style and a winner.
These are the things I didn't think through and am trying to get used to now. The big issue for me is that since it is a hard shell it is symmetrically split and needs to be opened completely flat to access things so the other half doesn't spill out. That requires more space which many hotels, luggage racks and my usual packing and unpacking place don't have. It may not seem like a big deal but the first time I walked into a hotel room with it and realized it needed to be opened completely "portrait style" instead of "landscape style" with the lid propped up I was struggling to find a place to set it.
The second thing I didn't check carefully was that it doesn't have any handle assist with lifting on any surface except the handle on the top and I'm used to one on the bottom of my luggage too.
I've taken it on 2 flights and several overnight driving trips so far. I love the look of it but I'm still trying to love the function of it, especially the laying both sides flat thing. If any of you use a hard sided bag can you offer any tips? I want to like this bag because it is a lovely bag in every other way. If you are thinking of switching to a hard sided case, please take these function changes into consideration.
