Hey Bryguy27007,

first off, i love that bike you have, i didn't buy one because i couldn't actually see one without having to pay for it first. beautiful bike. i hope you enjoy it.

I currently use the Ortlieb sportpacker plus panniers on the back with an Axiom Road Disc DLX rack for my GT Grade also with disc brakes.

i used to use the the Ortlieb Office Bag to hold my laptop and i still have this bag, but i use it more often when i'm in school. i commute to an office job about 4 mile commute and then from that job to school, another 3 miles away and then i go home after class. i usually have to pack a lunch, a change of office clothes, and when I'm in school, i also carry my notebook, school book and laptop.

generally i always keep one of the sportpackers on my bike - it holds my u-lock, rain gear and other miscellaneous things like a power bank and cord for my phone and lights and stuff since i dont have a dyno hub. in the morning, i usually place my lunches in this pannier.

on the other side, i place my clothes and random other stuff i might need for the day and this the pannier that i take off the bike when i go to work, and when i'm in school i swap that pannier for the office bag which in addition to my clothes holds my school stuff.

i keep shoes and hygiene stuff at work in a locker.

initially i strongly considered the topeak offerings and because it was my first ever rack and pannier set up, i went for something that had a little bit more carrying capacity and more waterproofing to it. in hindsight however, i think the topeak and the trunk bag with expandable pannier pockets would have served me well except i dont know how that would work inteh rain if you only use one pannier or something with their rain cover.

i hope that helps.
