Since you are already using medium format and have found yourself in a rut, why not look into a mamiya 6 or 7? they are wonderful "handhold" cameras.
I too use a hasselblad, but since I bought my mamiya 7II, I find myself shooting a lot more and seeing things much differently. It's a bit of freedom I guess, since I don't use a tripod much anymore.
As for the mamiya optics, I don't think there is anyone here on apug who would find fault with their quality, sharpness, or color rendition.
Take a look. You can get a M7 with an 80mm lens for about $1500 or so.
