To choose a Bam case, the most important factor is your budget. If you have a budget of $500, then you may want to choose one of the standard Bam cases instead of the Hightech cases.
If you do have the budget, and the lightness of the case is a top priority for you, we're confident that you'll be happy with a Hightech case.
If you have a larger shoulder rest that you prefer to keep in your case, we definitely suggest one of the oblong cases.
Keep in mind, Hightech slim cases are more spacious than the Hightech contoured cases, but the slim cases actually do not have enough space for a shoulder rest.
If you're a traveling musician that flies budget airlines with strict carry-on regulations, then you may want to consider a Bam cabin violin case.
If you're mostly flying major airlines, then the contoured case will be a good travel case, since most airlines still accept this as carry-on, plus you can keep your bows in the case.
Choosing the right Bam case really depends on your personal needs.
And probably the most important, choose the style you want! We've helped many violinists find Bam violin cases that actually had nothing to do with their initial criteria, because they saw a case that just looked absolutely beautiful!
Remember, these cases are durable. You may be carrying one for decades. Choose one that you'll be happy carrying around.
