I have just been looking at the Ortlieb Back Rollers...and the cheaper Tioga verions of same size. Not too comfortable spending over about $150-200 right now. Still very nervous about putting the laptop in a pannier, but keen to try getting the bag right off my back. I had toyed with carrying just the laptop on my back with the rest of the stuff in a pannier, but I'm coming around to the idea the pannier won't destroy it.
Heel strike issue had ocurred to me. Size 45/11 cycling shoe >> is it a question of buying a rack that goes far enough back? I assume Ortlieb have thought of this.
My personal experience is that your laptop will be OK inside the backpack inside the pannier (it's kind of like those little Russian dolls, isn't it??). Only you can decide if the $$$ are worth it. I'll encourage you all I can, but in the end, your wallet needs to be happy with your decision too.
RE heel strike; this is a combination of a number of factors including the rack, the way the rack is mounted, the bike and the pannier. I would strongly encourage you to take your bike to the LBS and ask them for help finding the right combination of rack and pannier. My LBS plonked my bike onto a trainer, then installed the rack and pannier. I got on and pedalled and ensured all was good.
The Ortliebs are quite adjustable, but it's best not to assume that this particular pannier will fit on that particular rack mounted onto that particular bike. Different panniers have different mounting schemes. If your LBS wants to make the sale, they'll help you out with this.
