You’re definitely not alone in that, a lot of people struggle with the restraints… Probably the most common complaint I’ve heard!!!Now this is entirely my opinion rather than a reasoned argument
The main reason I rate the RMCs I've ridden so low is the trains. I cannot stand the lap bars on Zadra (and Iron Rattler is just a poor ride sans the first drop) the layout was pretty good but the ride was ruined by those trains.
When I was at EG on a very quiet day I rode Zadra twice and that was enough (and this is coming from someone who's top 10 is almost all highly intense rides) where as I probably had 10 plus on formula and hyperion. And it was a similar story with Rattler. One ride on that and 5 plus on Superman and Goliath.
I'm sure one day when I ride some more RMCs (damn you covid) I might change my tune but so far I haven't got the hype.
As a larger, and more importantly, taller person, I find them to be some of the more comfortable out there. I struggle mostly with over the shoulder, and trains with less leg room like millennium flyers…
But I can totally understand why a train being uncomfortable to you would put you right off. I can think of a couple where I don’t actually mind the roughness, enjoy the layout, but cannot abide the restraints… Colossus for one! I will never, ever ride that coaster again, not because it’s rough, and I actually like the layout, but because the restraints try to break my shoulders and ribs every time!
