Personally I loathe TLRs because of the handling. Hasselblad + 80mm is a lovely package but any other lens makes it too heavy and bulky for my taste, at least once it's off the tripod. For results and versatility, it's a Linhof Technika every time. Or (if you can sacrifice some versatility), an Alpa, though that's serious money. But I'd not consider the vast majority of folders (especially with Tessars) because so few of them are sharp. I love f/6.3 Tessars. Anything faster is an unacceptable compromise in my book.
For large head portraits, either a Leica with 90mm (Summicron or Thambar, for completely different looks) or 8x10 inch De Vere with 21 inch f/7.7 Ross.
The only reason for this post is to point out that there are lots of other options and opinions.
