Hi, yes a frame with rollers would be much easier than a hoop. You just roll away the fabric your not stitching on. As you would be starting in the middle of your design, you would be storing the rest of your fabric on both the top and bottom rollers and as they have wing nuts, well mine do anyway, you can keep your tension correct and then just roll the fabric up or down as your design progresses. Also with frames you can leave your stitching in it, unlike hoops where you have to keep taking it off to avoid leaving marks.
You would need a frame a couple of inches bigger than the width of your fabric, my frames are made from wood, which I think is more robust than plastic, but it's down to personal choice, some frames have clips to attach your aida to the roller, some have a strip of fabric attached that you tack your aida on to, mine are the latter, but it only takes a few minutes to do.
I also use a lap stand to rest my frame on, it makes stitching much easier.
Hope my explanation makes sense, if not let me know and I will try to answer your questions.
