Default Solder vs crimp?

I've always been a "solder" person for connecting cables to connectors, but I'm just in the process of putting some ring terminals on 4AG cable for the p/s caps. Soldering this size doesn't seem to really be an option. So will probably crimp, but I wanted to hear other views on pros/cons of crimping.
Thanks

the biggest (hugest ?? ) solder on spade that I ever saw is in Wilson Watt-Puppy bass cable, it's HUGE , so soldering is still possible.

The biggest (hugest!) problem is getting enough heat in to get a good solder joint without melting the insulation (which isn't teflon unfortunately). I've tried a blowtorch but still didn't give good results - maybe I need to get a 200W iron....

yes I know, blowtorch doesn't seem to do very well (because the air is not a good conductor of heat ?). I should've checked what insulation they use.

the bad thing about crimping is when the crimping connection is not perfect and develop oxidation at the contact point. so dissimilar metal could be troublesome on the long term.

another way is solder multiple smaller cable on separate ring and connect them together using copper bus bar.

I don't have a big enough crimping tool to do something like that and don't have a blowtorch either.

what I do is lay the connector on an anvil of some sort and bash it flat with a hammer.

haven't had problems with it.

I donīt have crimping pliers, so when I want to use fastons, I first crimp them a little with normal thin pliers (or a srewdriver and hammer or anything else), and then when it holds together I solder it.

OK, I picked up a 175W soldering iron today and the results are good. I can get a good connection with minimal damage to the insulation, so I think I'll go this way. Tries a few of the crimping options suggested and results are ok, but I'm still not convinced the connection is as good as solder...
Thanks for your comments
