I'd try and re-use the spokes. While I have had many broken spokes on rear wheels I have rarely broken a front one.
The spokes on a 24 spoke wheel may not be ordinary spokes, the kind that cost a buck or less.
They may be expensive and they may be stronger than ordinary spokes since there are fewer of them.
I recently got a disc only monstercross bike and I love the brakes.
What kind of disc are you running?
