egt or o2 sensors?

I have a blown alcohol altered 1500-1600 hp with double wall funny car zoomies. Just picked up a DL 32 data logger. Now I need to decide if I should run 8 egt's or 8 o2's and/or a combination of both. The o2's are quite a bit more up front; about $200 each and the egts are $60 each (already have the amplifliers for the egts). Looking for your experience. Also where can I get the best deal on each? Thanks.

 

Speaking from personal experience on 2 teams that tried, as well as talking to others that have tried - I doubt you will get any readings from the O2 sensors.

These things run too rich and there's just too much unburnt fuel.
