I always thought the Fusion bags looked great but were hard to find and expensive. And I could never get a feeling for how big the many, many pockets were. Now seeing those pics of it (thanks whoever posted them!), I'm not a fan. I don't like all the foam padding inside it. Looks like a PITA if one loads the bass as I do - from the top.
I always lusted for an iGig as well, but looking closely at the pics, the side foam looks on the thin side.
Just don't like the Reunion Blues stuff. Not enough pockets and look flimsy. Also, if the bass flops around inside as it looks like a Fender might, that's not good.
On my last inspection, the Mono seems to be a very protective case, but I thought it was more expensive than it had to be.
I settled on a Gator ProGo some time ago out of frustration about not finding anything that checked all the boxes for me, but I have come to like it a lot. The only thing I don't like about it is I wish the bottom pocket were bigger. I had a bag that was not as good, but had a gigantic pocket into which I could put a class D amp. I got spoiled by that.
In the end, it's a bag after all, and I would never use a bag in places where I'd need something tough. But I would use the Gator if touring and the bass was with me all the time.
