I assume you know about the unsupported bit beneath the first drop!
Slight issue with the transfer track as shown below:
As shown below - I'm not keen on how you've supported this here either - looks flimsy with the crooked supports as the support that is set inside will be under an unusally large bending moment. I think you'd be better off shifting the entire support laterally and have a little cantilever at the top where it connects to the lift!
That said - I really
really enjoyed the ride. The spin rotations were great, support work fantastic and consistent (bar noted errors) and felt like it flowed really well. I think you've done a good job of creating a compact (for the nature of this type of ride).
