Then I found Gearloop 44/28 chainrings and I went for it.
Gearoop 44/28 direct mount chainring weight about 130g, cost around $140.
I pair it with Quarq Dub crank arms, weight 339g with some unnecessary plastics. This crank arms cost me $196.
Together, this tiny compact crankset weight under 476g without unnecessary plastic pieces. Using 28t front ring together with 11-30 cassette in the back, I now have sub 1-1 gearing, while also having relatively tight jump between the gears. It shift pretty nice too, although I need to shift a lot of gear in the back to compensate for the big difference between big ring and small ring (still 16t difference but ratio wise it is more than regular compact).
On scale:
Initial installation, with front derailleur set way too high for 44t chainring.:
I have to move the blaze-on mounting tab a bit lower to mount my FD low enough for proper installation. To be honest, it shift the same as when the FD is way too high. I guess by moving it down, I just reduce the chance of overshifting and drop the chain on the outside.
