Hi Ben-
My two cents is any upgrades, or really anything else you want to do to the bike, is subjective.
First thing to me is will the bike be used, and how will the bike be used.
Sometimes those are simple questions to answer, and sometimes not simple to answer realistically.
As you know from reading this forum, there are folks here that never ride their Vin, all the way to folks who tour on them far and wide regularly, so the answers to your queries would range accordingly.
Myself, I originally went 12v for improved night time lighting; having the stock gen converted, along with a JG unit.
I would not do that today for two reasons; first LEDs have come a long way and I'd now do 6v LED lighting instead of converting, and secondly, I found when I hit my seventies that compromised night driving vision, so then lighting, other than being seen, became a non-issue.
I used my covid time to replace both knees, a very worthwhile venture, and am at the moment recovering from hernia surgery.
(yes, with new knees I thought I was twenty years younger, and acted like it, till the rest of the body said hold on just a tick..)
So wanting to protect all that work to the body, I'm in the process of installing a Dave Hills stand and the Grosset electric leg.
And then there's always the personal debate concerning staying standard in appearance, or prioritizing modern comfort and safety over having "the look."
The point here is horses for courses; identify your course first.
All legitimate questions to know and understand about both where you're coming from, where you want to go, and where life takes you regardless of your intentions.
