I'd go for using SMA, etc. at microwave frequencies. And I'd much prefer 
a crimp connector over a solder on connector as well (and so do people 
who worry about reliability, etc.).

Solder SMA on semirigid is asking for microcracks, etc. at the joint. 
Crimping is more reliable, gas-tight, etc. and stands up to vibration 
and thermal cycling MUCH better.

The disadvantage is the $500 in tooling required to install the connectors.
