Yes, if you can't get gold, the brass are a bit better, worth the couple extra bucks anyway. Solder/clamp will keep a better connection(or so they say) the ones I made were just the clamp type and they work just fine. Just make sure that the wire insulation goes all the way up to, if not in to the terminal, otherwise you're askin for bad things to happen.
If the snow ever melts, I'll take a pic of mine and send it to you so you can see what I mean.
