The Westbury double bass case is the one that you want for your situation, as others have already said. The number of handles and their placement make it an excellent choice. Some dealers rename them as their brand of a case; this is a testament to the Westbury's quality.
[b]Endpin Damage:[/b] Most bass bags/cases zip up to the endpin. There are a couple of reasons for this:
A, To prevent damage to the case and zip
B, To make them easier to put on and off the bass.
Most good cases including the Westbury have leather (or similar) sewn over the zip to prevent the zip being closed completely over the endpin. Cases with an offset zip and a hole for the endpin to poke through are a real pain to get on and off the bass.
In this photo, you can see the zip stops sewn over the Westbury case zip. [url="https://www.bassbags.co.uk/img_0310/"]https://www.bassbags.co.uk/img_0310/[/url]
