Following a few changes in the bands I'm now playing in, I now only need to take my full kit to gigs with both rehearsal studios having at least the drums in place with me just adding in my own cymbals and other bits and pieces as necessary. Consequently, I'm looking for a better way to transport/carry the items I need for rehearsal without having to take my full hardware case; essentially looking to be able to travel light whilst still having everything I need. I'm looking for something not overly heavy but will still stand up to wear and tear. The idea is that I want to be able to carry all I need in by hand; one hand for my cymbal case and the other hand for all the other bits. The kind of things I'm looking for this bag/case to carry include:

Tambourine and mounting bracket
Cow bell and mounting bracket
Stick bag (usual mid sized)
Moon gel
Various spares such as snare wire straps, kick pedal spring, hi-hat clutch, etc.
A4 folder containing charts
Pens
Drum keys

I've come across a few options online such as this one from Hardcase but would welcome any input from those with experience of such things.
