I also consider buying 111 but I wondered how much different it is from 107 or 117 because I have no knowledge about these boards.
The 107 is the successor of the 111. Same width, probably almost the same volume. Starting from 2011, all boards carry more precise volume specs.
I agree with most replies above, i.e. if you're aiming for the lower end, then forget about the IS107 (or 111) but go for the 117W (80cm) but also go for a bigger sail next to the 7.8, at least 8.6 or 9.5.
