New Moto Guzzi Door Mats Available Now
I used soft bags for years, and was quite pleased with the set I used. I bought a set from, http://www.revpack.com/saddle-bags/ I found them to be excellent quality, and very adjustable. I used them on my 1100 Bassa and later the 1100 Breva. They are pretty stiff, and have snap straps for keeping them from moving around. I have the foam sided deluxe, which I would recommend based on your requirements. I would still be using them if I hadn't scored a killer deal on matching hard bags!The deluxe bags have the added advantage of being insulated, thus making them excellent coolers! I'm pretty confident you could use them with ease on a v7. Soft bags have their limitations, but they do have one very big advantage, they come completely off in seconds, with no after taste!
I have a Stucchi rack (similar), with the C-Bow system on my V7 Special. The rear mounting point (fender) for both the rack and C-Bows is doubled up. No problem.
