Spoke Calc Day !
 

So I ran these through my favorite calculator program (Sheldon Brown) and got the below numbers. If anyone has the time to run it through their fave program I'd be interested to know if there are any differences.
TIA

Hubs are DA7700 front and rear
Rims are Mavic CXP 33 front and rear 28 spoke (even spoke spacing of course). The calculator called up 598 as the erd as I recall. Some may use 597.

Front wheel 2x = 288.7 which I would round up to 289

Rear wheel 3x = 296 left, and 294.4 right which I would round up to 295. Actually I would probably use 296 on both sides as 1mm long is NBD in a rim that deep
