I have a plan to buy Power2max power meter (4 holes version specifically to use Shimano chainrings, but that is irrelevant to the question).
Apperantly, Rotor Aldhu in 110-4S weight 610g and cost 790,00 €
while
Rotor 3d+ 110-4S weight 590g and cost 690,00 €. Which seems to be a better deal.
There are also some minor difference in chain line (43.5mm vs 45mm) and q-factor (148mm vs 149mm).
Can anyone tell me what would be the reason to pick Aldhu over 3d+ ?
A lighter option than both would be FSA K-force Light crank arms, but from my past experience, i don't fully trust FSA's quality...

one main advantage of Aldhu is to be able to adjust the OCP for their oval rings. i dont think going down the P2M route allows you to do that. (i went down the aldhu non-power crank + P2M NGeco route).
Some say pour 10ml water out of your bottle to save that last bit of the weight. Sorry, i go one step further, i tend to the rider off my bikes.
n+1...14 last time i checked, but i lost count

Rotor oval 4 bolt chainrings alow you to mount them in 4 different positions (4 OCP).
Next:
What spindle to use on road disc brake bike (with power2max 4 bolt version and Shimano rings) ?
There is a standard spindle: chainline=43.5mm q-factor=147mm
and
offset spindle: chainline=46mm q-factor=152mm.
While Rotor suggest offset spindle for disc brake road bike, original Shimano crank use 43.5mm chainline and it work for both rim and disc brake.
Should i try to match Shimano spec or Follow Rotor's suggestion of pushing chainrings 2.5mm further out for disc brake bike?

If you're going BB30 for road and you can get ahold of the spider tool, it might be a good idea to get a used 3d+ Crank, as P2M charges $200 and is out of many sizes.
I'd do the Aldu for a Gravel bike (direct mount rings) or if you're going to between BB30/BB86 as you can change spindles.
