Gard 13-WBFSK Trolley f. Trump/Flug

Purchasing this case has been a weight lifted from my shoulders (if you'll pardon the pun)!
The trolley is perfect for my requirements; lots of space for all my equipment, durable to allow for frequent use, and the wheels take a lot of the strain out of my back and shoulders.
While quite pricey, I use this bag every week, and it has yet to show any signs of wear.
The only issues I have with this case are those due to weight and size. These cases are very wide and deep, as to allow you to fit all your equipment inside, but completely filling the case will cause it to become very heavy and difficult to manoeuvre, and while these cases are small enough to fit on trains and coaches, they do take up a lot of room when packing cars and vans.
For those interested to see if they can fit all their equipment, I carry all of these inside my Gard Trolley with room to spare.
Yamaha Trumpet
Thomann Flugel (heavy)
Mouthpiece pouch
Shure SM57 and SM58 microphones and clips
Clip on mic (with power pack)
Mic stand "mini-boom"
Soundback shield
Trumpet stand
3 x Long XLR cables and 2 x Jack to Jack cables
Battery charger

With space to spare and without putting anything in the front pouch (space for clothes etc.).

Fits both my Yamaha trumpet and my Yamaha flugelhorn, is sturdy and seems to be of good quality, but I find that it is a bit impractical to use.

The bag "flap" does not open all the way, so especially the flugelhorn is a bit fiddly to get in. You have to use one hand at all times to hold back the flap while maneuvering the horns in. A couple of centimeters longer zipper on both sides would have made a huge difference!

It could have made a difference if one could position the bell of the flugelhorn against the top opening, but the bag is not wide enough at the top to fit the flugelhorn bell. This limits the otherwise many options to customize the inside of the bag, making it fit two (or maybe even three) trumpets better than one flugelhorn and one trumpet.
