There is a real advantage to registering it as an homebuilt rather than special light sport. A S-LSA (special light sport aircraft) must be maintained, repaired and modified per the manufacturer's instructions.
A homebuilt does not require the manufacturer's blessing to maintain, repair, and modify. As the builder of a homebuilt that happens to meet the LSA requirements, you'll have the right to be its mechanic and do the annual condition inspection.
The 750 is an amazing machine.
