I would say a F93 & F122.
However after sailing the 107, you will find the Futura's a little like sailing on autopilot. The most versatile Isonic is the 107, and the 111 for the Futura. I find the dimensions somewhat puzzling for the 101 Futura, having the same tail width, and marginally less width than the F111. The F93, I believe is also too wide for its volume and can become very big quickly esp with an 80kg rider.
I would suggest keeping the I107 (8.6,7.8,7.2) trying a F93 (7.2,6.2) and keep your I87.
