Ed,

If you are using #10 wire, I would rate that at 30 amps.  That gauge 
wire will just barely fit into the 30 amp APP connectors, and I prefer 
to use the 45 amp connectors for #10 wire.  I think your use of the 75 
amp APP connectors is overkill.

Yes, the proper crimping tool is mandatory IMHO for APP connectors of 
the 45 amp and above rating.  With the 30 amp and below connectors, 
soldering is a possibility, but not for the larger current rating 
connectors.

73,
