The two tech charts are broken into four appropriate areas (as mentioned in my expansion rules file). The chart itself can be cut out and fits inside/under the lid of each nation's components box. I've kept the heavy bombers at 2d6, since a player can now "focus" on more particular tech. to combat SBR's (ie: war bonds, radar), and if you use the Fighter Interceptor rule that I've included in my expansion (also used in other A&A editions)... then bombers should have a bigger punch to make it worth it (and I like heavy bombers to be HEAVY :) But its an open excel so anything can be changed (I've added some description to each tech as well, when space permitted). Oh - and some feedback and results while using these charts would be nice...
