Best DIY silver solder?

I agree with the above post....Don't solder, CRIMP, and heat shrink them. Check out the Furez line of pure copper spades and bananas, which can be re-used on different wires you may be experimenting with. They use hex keys to tighten down to the wire with, and can be easily removed. If you don't like the wire you are experimenting with, you can re-use the terminations.

I crimped and then soldered heating wire first to avoid thermal expansion of the connector.  That way it keeps direct oxygen free connection and it is strong.  I used WBT solder but it might not make much difference since the solder is only 4% silver.

Thanks so far guys for your replies! Very useful info! 🙏🏻
