yes lantern are better, but they are Const6.

I've just performed a test game, Const4 can be reached on turn 14 with only 4 research turns from a rainbow pretender (he had 23rp). I dont want to loose more time in construction, dooing this I had Conj5 thau6 evo5 ench5 alt3 const4 (well I went all magic path because I simply dont know what to research) by turn 35 (+burden of time and foul air up). I dont know if this sounds good, yet it was enough to get rid of the mighty AIs (I set indep strength to 8 and it seems it was definitly too high for them ^^)
