would go for a good 42 with the 110. You can go in pretty light conditions with that board with 8,6. Starboard recommends excellent fins for their iSonics.
The fins for the 101 are fine.
For the 133 a 49 makes sense.But you will use the board with the 9,6 most of the time and then switch to 110 with 8,6.
Hope it helps,
