I was thinking about the VFR as well, but I watched several review videos and they pushed me towards the Africa Twin. Even the salesfolks at the dealerships I talked to suggested AT over VFR. These videos really highlight the differences between them.
Around 13:35 of the VFR video, he says something like, "Why buy the VFR when you can get the AT for less?"
Everyone I've talked to has been positive about the AT and down on the VFR for various reasons. On paper, the VFR seems more like the type of bike I'd enjoy, but I just went with the reviews and got the AT.
What made you feel like the 700x was too light?
