Okay so I need your advice/opinions on the best thing to use for a Premier Launched coaster that simply will go down a track, then head back to the station in reverse. I'm using a simple B&M track which is fine but I need a good car.

Premium Launched?

I assume you mean... Premier?

Lol I was a bit tired when typing this!! lol thanks yes sorry

Dont use the B&M track for the ride, I would suggest using the Krypt launched coaster CTR for more realism (also allows for diagonal curve inclines)

Seconded. Also, look for The Coaster Essentials LIMs which is a CS pack that includes Premier style LIMs. They will help making the coaster look for like a real Premier launched coaster
