Okay i found two more weird coasters on rcdb
1. In the same country that has that weird spiral lift coaster, that air launch tower with the lose restraints and that unopened formula 1 coaster, there is also these two duelling roller coasters known as Slalom & Tornado:

2. The second is from the UK and is a weird suspended coaster that operated at the Shipley Glen Pleasure Grounds from the 1900's till it closed in 2002 and was torn down two years later.
