so mopar alts are just bad at idle.
however, you can up your amps by just going to a square back alt.
ground one field wire and you can continue to use your stock voltage reg with no other wiring changes.
These are 50 dollar alt from any parts house.

putting your lights on relays, putting as solid wire through instead of the bulkhead connectors for main power might also help.

or you can step up to several of the higher dollar ones as you listed.
BUT I prefer to use something more easily access and replacable from the parts house.
like the early magnum ones, or the toyota ones they replace the pulley from.
