I've come to think a good TLR is the sweet spot for travelling light with MF---good focussing mechanism, good lenses, manageable weight and bulk---but you generally have to accept a fixed lens, and again it's hard to get built-in metering (and if you do it's usually selenium).

The Rolleiflex GX and FX TLRs have modern semi-spot metering.
