Agreed. Half the time with the insulated crimps I end up "biting" off the insulator with the crimping tool because I squeeze too hard. It's either that or the wires slip out when I tug them to check the crimp.
I use a heat gun. They do a nice job and don't burn the insulation. I also get sealing heat shrink, prevents moisture from getting into the splice. you can see some of the sealant on the wire.
Thanks Joe! I like how with the uninsulated, you can see the crimp much better than with insulated. I pfrefer the indent crimp as well, makes a way better connection.
Does Home Depot and Lowe's sell these heat shrinks?
