Cannondale Si cranks - spiderring ?

[ednino]

my 2015 CAAD10 has Si cranks with a 110bcd spider & praxis 50/34 chainrings (133g for the rings)

Would the cannondale own spiderring be lighter? As it doesn't need the adapter or any chainring bolts?
Thoughts?

Yes, the spidering would be a bit lighter but I would stay with your current setup.
