Apologies for forgetting this thread, my father passed away a couple months ago and my head is still pretty messed up from that. I haven't even been on my bike since then and that is making me feel even ****tier, the PNW winter weather isn't helping the matter. But, I've gotta keep pushing forward...
I decided to go ahead and upgrade the crankset as well, so in keeping with the vintage theme I found a Sugino Super Mighty (144bcd) and I'll be using the 42t drilled inner chainring that came standard on it. Just like my previous combo, I ditched the outer ring in favour of a BBG bash guard and detailed the arms in black.

A nutted spindle like yours will be solid all the way through, whereas a hollow spindle is lighter without giving up much (if any) strength. And the aluminum cups on higher-end bottom brackets save additional weight. On my rando bike, I went from a 286g Shimano UN55 to a 247g Tange-Seiki 7922, and that is in spite of going from a 107mm spindle to a 118mm spindle for a different crankset! So if you're not changing the length, you can do even better.
I finally properly measured my current BB spindle, looks like I'm right about 125mm. I wouldn't mind adding a few extra mm's for chain stay clearance on future possible upgrades. I also need it to work correctly with the Super Mighty square taper crank (whatever type square taper that is). I like the idea of aluminium cups. Any recommendations on where to find/compare/buy bottom brackets like this? Thanks again-
