Why? Crimping is far more than adequate especially if you use factory made heat shrink crimps.. Also, twisting of wires together, even with solder, is not ABYC E-11 compliant. You don't need to wire to the standard but it is always a good idea especially if you ever go to sell or need an insurance survey. We have a couple of surveyors up this way who will flag solder only connections as "noted" items.
