There was nothing inherently wrong with Hoyt singlecams. To this day, many prefer them for several reasons. Hoyt made a decision to go with all hybrid cams. To me, this is more of a marketing decision than one designed to help hunters. There is no reason you can't tune the singlecam to shoot your broadheads to where you're aiming at release. My only recommendation on single cams is to shoot the highest quality string and cable. I prefer custom made Ultracam strings. They will not creep when made properly, which will help keep your single cam in tune.
