I was speaking in a more general sense (i.e. "I don't like loops, at all"), but even when talking about specific elements, I still struggle to come up with any that I really dislike. Sure, the entrance to Arrow corkscrews are often a bit awkward, and sure, Storm Runner & Maverick give a bit of neck-chopping on their snappier inversions, but I enjoy those elements as a whole.
Airtime Hills and Sea Serpents. Of course we pretty mcuh all love airtime, and I like Sea Serpents because they have positive g's at the beginning and they all just realease and before you know it you're upside down with a little bit of floaty airtime. Then you think you're in a Cobra Roll and then twist upside down right in another direction and just dive right into the next element.
I still have to stick to pretzel loops (although I have only been on Tatsu's, I imagine it's the best). Sitting in the back row, I got a real surprise of heavy Gs. I really haven't felt anything like that with any other element.
After my recent trip to Orlando, Montu and Dragon Challenge/Dueling Dragons reminded how amazing corkscrews are on B&M inverts. Just the exaggerated motion around the element, and the fact that it isn't pure g-force because I feel a slight freedom and sensation of being pushed out of your seat instead of into it like in a sit-down. Hands down, corkscrews on B&M inverts.
