MABLI!!! You totally rocked the Cinn GH PT~!!!
As far as the handles go on the Giant Hardware PT.. it well definitely fit over most shoulders (speaking which because... I have big ol' arms)... and they fit over mine, with a sweatshirt too.. or a thin coat or cardigan.
The GH Work... takes a little more use with effort to have fit over the shoulder.. but I noticed that I had a hard time keeping the handles on.
The GH Brief, I've only tried on at NM. I found that the RH Brief handles stayed on better than the GH. But, the GH Brief... has a lovely sag once its broken in.. and the handle space will probably give more once its broken in.
The RTT... I've only seen IRL.. but never tried on.. and I by the looks of it.. it has ample room for shoulders. It's a pretty large bag.
