I love my small Sonicase. Super compact, great access, and best of all it's made really well (imo). It reminds me of the Portabrace I used back in the day.
Enough room for mics, pre, 7##, and a few accessories. I keep a couple secondary bags with all the extra stuff and just rotate in what I need for the show. It has worked especially well in those tight settings up front.
I walked into Shea's for Furthur without it even being noticed at the front doors, when other bags were getting torn through. For the little bit I carry, I wouldn't use anything else, and could still add a pre and be fine.
