It all depends on who's working on the ride at a specific time. The crew last year did a decent job, but there were some times when it definitely lagged in operations. I've always said that Banshee is/should be a line eater as well as Diamondback and Orion. For those unfamiliar with the term, a "line eater" is defined as thus:
Line Eater-A roller coaster or attraction that is able to "eat" a line and decrease the wait time due to high rider capacity. Examples could be Diamondback, Orion, or literally any B&M!
A "line holder" is similar to a "line eater", but slightly different:
Line Holder-A roller coaster or attraction that holds many people in line and is sometimes a very popular ride. It doesn't have a high capacity compared to other rides. This line sometimes takes away from the other lines, making them shorter. Examples could be Flight of Fear, Top Thrill Dragster/TT2, any type of shuttle coaster, Steel Vengeance with one or two trains, and probably Siren's Curse when it opens (these are just a few)
All that said, hopefully Banshee can still be a line eater. I remember during the Haunt last year when the lines are already insane and Banshee was running one train. It was disastrous. I don't think people mind waiting in the brake run for a minute or less, but if something is wrong, those Vest Restraints make it really hard to breath and it starts getting really hot (I don't know why they used Vest Restraints on Banshee. I'd rather have the regular Over the Head). I'd prefer them to run 3 trains, but if they have to, I can live with 2.
