Recommendations for the perfect pouch

All right ManyBaggers, I need your help!

I'm in the hunt to find the perfect pouch for my carry. I just got a Lenovo LEGION Tab Gen 3 (aka LEGION Y700) and I'm looking for a pouch to carry that as well as some extra accessories like a GaN charger and cables, in addition to a loaded up small pouche like a Data Crew What-A-Jr. Bonus points if it can be converted to a sling and has MOLLE or loop fields for patches

So far, I've tried:

• Alpaka Elements Tech Case: fits everything pretty well, a little too puffy/padded
• Alpaka Elements Tech Case Mini: does not fit the tablet
• Dan Matsuda Article 044: does not fit the tablet
• Tom Bihn Side Effect: fits everything a little uncomfortably, but good size. Probably needs another half inch of height
• Evergoods CAP2: fits everything pretty well, a little too much depth/padding
• Step22 Tiger Trove Standard: does not fit the tablet
• Waterfield Designs Air Caddy (iPad Mini size): sort of fits stuff, tablet compartment is tight

Next up under consideration:

• Bellroy Desk Caddy: seems like everything should fit?
• Nutsac Double Admin: probably is the One, expensive
• Triple Aught Design Organizer: probably will also work well, also expensive
• Waterfield Designs Tech Pocket Mini: seems like it would only hold the tablet

Ideally, I'm looking for a roughly 9 x 6 inch or 23 x 15 cm pouch (basically a little taller than the Side Effect) that I can move between my various bigger slings and backpacks.

Show me what you got!
