I have both the 2 wheel and 4 wheel spinner. Just get the 2 wheel and call it a day. That lifetime warranty and build quality can’t be beat. One of the biggest downsides is when it gets gate checked it can be mistaken by someone else. Personalized luggage is the way to go. Oil marker and spray paint. The 4 wheel spinner is just a durable but I hate the way it feels when on concrete. Change is good and luggage works makes a quality product too. Just a brand whore at this moment. Given B&R have taken care of me throughout the years of 50+ flights annually.
