Recipe uses Warrior, Chinook citra and mosaic plus missing Eldorado.
Have in varying amounts: fuggles, EKG simcoe, saaz, first gold, mandarina, perle, challenger, celeia, bobek, cascade and hersbrucker.
look at the site phildo 79 has put a link to excellent info. Me personal i would from what you have got put 50% extra Citra and 50% extra cascade but who knows?
Just realised you have Simcoe that is a sub that is listed on the site maybe use that 100%
