I've used iGig bags for the last couple years and have been as happy as I can imagine. I've flown with them a number of times, too (onto plane, putting it in the coat closet; not checked in!). Couldn't be happier. I like Mono cases, too- I just happened to get iGig first.
I'm not so much into the leather bags. Not enough protection for me.
Wow - Until now I've never gassed for a gig bag but these leather bags are killing me. That LM19 isn't a bad price either (at least the black one isn't.)
Any other finish apart from the Black LM19, and your looking at a considerable price hike, but it's a great bag.
Angus, I'm inclined to agree with you, I think the issue is about the padding; it may not be as thick as I'd like, plus I wonder how good is protection for the heel. Sometimes the bass gets a bump on the rear and It's reassuring knowing there's a little more protection in that area.
