Crimping is only easy to do if you have the tool and are proficient in 
its use.
Some of us need soldering only advice-like where not to get the solder. 
Power pole connectors are "new technology" to many of us.  
Given the problems I've had with past crimping tools, the first couple 
crimps with a new tool/connector are bad.  That shoots down the two 
connectors supplied.   So I guess if I had to buy a tool,  I'd also get 
a bunch of "spare" connectors too.  Not the scenerio I like for a $2K rig.
Not an big deal though.
