A Vekoma Boomerang is not hard to recreate in my opinion, so that's why that one has a bit of a lower score. The ride itself: the layout is okay, I recommend adding some rolls so that it's less shaky. The track "shakes" sometimes and that can be fixed easily. Also you might change the first lifthill. The part where it goes from a 45 degree angle to flat is too small. That causes too high G-forces (5,7 G). Realism: It was realistic: I liked that you added a catwalk in the cobra roll, that really adds to realism. As a tip: Add a brakerun before the second lift, those are there also in real-life. Overall a good recreation that just needs some work
