Over the years, I have greatly preferred top loading bags, particularly the Gotz gig bags. However, with piston tubas, I think side loading bags might make a little more sense (less chance of the valve stems getting snagged on something).
I have been considering Cronkhite bags, but the costs are really getting up there. Also, I had a chance to buy a used one a while ago, and I honestly didn't like the way a moderately used cordura bag looked. Overall (plus the pouch in the front), it just started looking frumpy. I'm sure the protection was still top level, but it just didn't look great to me.
Leather Cronkhite bags are probably the gold-level protection, but are also gold-level price. Not out of the question, but its a significant investment.
I've heard that Gotz can make side loading bags, but I'm not certain about that. Might be an option, but if it's not something they usually make, I don't know if I'm as willing to try it out. Relying upon expertise from the manufacturer seems safer than special orders. Side loading bags scare me, because if the zipper breaks...
Anyway, some rambling thoughts here. Not sure I even asked a question... Just not sure what I want to do. Welcome opinions from you all.. will probably order something by Monday
Thanks!
