Bent derailleur hanger led to repeated chain-drop, which damaged every other drive-side spoke. My lovely LBS (love them) offered to order the 6 Sapim Laser spokes I needed -- but what arrived were DTS C-Race. LBS assures me the spokes are nearly identical, but I confess to being a bit particular...and I know the DTS spokes are slightly thicker (1.8 vs 1.5 i think), and when I set myself to repair this wheel I'll have three different tensions in play, won't I? 12 Lasers non-drive-side, then 6 Lasers crossing 6 C-Race on the drive side.

(1) I know you CAN mix spokes and the earth won't end. But would YOU forge ahead with the mixed spokes in my situation? I can always buy more spokes...
(2) would you de-tension the entire wheel, replace the 6 spokes, then re-tension as a whole wheel, OR just replace & retension each damaged spoke, one at a time?

Thanks in advance!
