Hooked spades, for each gauge of wire, are ok; but whenever possible I recommend ring terminals. In order for them to come off the entire screw has to come out of the connection, something you will like be alerted to through intermittent electrical problems long before it becomes completely disconnected.
Some heat shrink tape or tubes is also a must have, to cover any butt-crimps you need to do.
Oh, and spend the money for a good quality stripper/crimper; don't cheap out and buy a dollar store one, spend the extra 5 or 6 $ and get a good one, you'll be glad you did.
I got an Old Fat Boat
She's Slow But Handsome
Hard In The Chine, but Soft In The Transom
I Love Her Well, And She Must Love Me
But I think It's Only For My Money
