Funny, that's the reason I don't like crimping.  I guess there's no "solid" 
solution (pun intended).

Doesn't it have to get hotter than normal soldering temperature for a few 
seconds in order to have an effect on elasticity?

Overall I've had better reliability with soldered connections, but that's 
just me.

Crimping is much faster than soldering, hence less expensive & making $128 
+ taxes roundtrip airfare from SoCal to MDW (for Dayton) possible  :)
