I come from a touring orientation, more spokes . 36 , and DT alpine if you want butted spokes ..
13/15/14. Brass nipples .. build with Anti-seize on the spoke threads
my loaded touring rig got 48 straight ga 14,
I have a racy bike , low milage .. even 20 years later [ 36 15 Ga straight ]

At 245 aero has a level of why bother ?

+ bladed spoke need hubs holes cut for clearance, to get the blade thru.

That weakens the Hub flange stick with round /DB spokes ..

But if you want light wheels build 2 sets , 1 for a backup.
