Thanks all for the great answers. I'm waiting on aerodyne to come back to me about it.
Onto the subject of preferences, I've got to test quite a few containers so far, and I absolutely loved most the I6 I tried. As to canopy size, I'm just about to downsize from a 200/210 to 190, going from a wingloading of 0.98 to 1.08. I believe that if I can get something that I will be able to use until I reach 150, I'll be using this rig for a good 5+ years, making it worth buying new(especially since it's an easy to sell range).
For those joking about it, it's not about getting a small container, I couldn't care less if the bag is 20kg and looks like a tandem rig, it's just about being able to use it in progression.
Thanks again for all the advice and recs, deeply appreciated.
