I'm a mid cap fan. I enjoy reloading and I also play milsim, which often won't let you use high-caps unless you're an LMG. I also don't like winding personally, Either you have to pull back into cover or not hold your gnu properly while you wind. Unless you are playing an event that restricts you though, it's generally personal preference. I've definitely gone around a corner to find my midcap empty... that's partly on me for not counting my shots though.

I'd go to a surplus store if you can, to try them on and make sure you get good support. Lots of people play in normal walking boots - personally I'd rather have the extra layer of support military boots provide though. If you get military style boots that are the leather/fake leather boots you may also want polish - put a layer on and brush it off but don't buff it and the boots will stay dull rather than shiny and it provides some waterproofing. Things to think about when looking fit and comfort (obviously) breathability/waterproof - generally waterproof boots are less breathable so if you only plan on playing when it's sunny and there is no mud you may want desert style boots that have more airflow ankle support - generally more is better but too much can restrict you movement (I find anyway)
