I use a 7II with a 65mm lens for walk-around journalistic and landscape shots and find it to be perfect for that type of situation. For me this camera/lens combo is extremely light for the 6x7 neg size, and produces very sharp results. I tried it with the 150mm and its accompanying viewfinder for portraits, but found it not to be for me. The 7II is my first rangefinder so that may of been the problem. I shot portraits professionally for 15 years with Hassy gear and became accustomed to the WYSIWYG SLR design. I found looking through the 150'mms viewfinder difficult for me to decipher a quick composition. I eventually sold the 150mm lens and viewfinder. I would suggest looking through the 150mm lens on a Mamiya 7 before you purchase it.
