Can't believe how many people here are trying to spook the dude...
Damn...
Conditions to be met:
1. If spokes were properly tensioned (nice and tight) previously...
2. If spokes were generally evenly tensioned previously...
3. If previous wheel had a relatively unexciting life - no damage to any part of the wheel...
Go ahead try to reuse the spokes...on one condition:
THAT YOU PROPERLY TENSION THE SPOKES AGAIN! (Nice and tight and evenly tensioned in the general sense.)
That fact that this is a front wheel makes likelihood of success even better. With the exception of disc-brake wheels - front wheels rarely suffer spoke breakage.
Have reused spokes (generic and DT alike) easily a hundred plus times - used to take a selection of used wheels and do a salvage job for a shop.
With rear wheels - take into consideration how generic the generic spokes are. It's a judgement call with rear wheels. If the spokes are DT Swiss spokes - chances are that 99% of the time rebuilding the wheel will work out just fine.
