Hi Sl, 50-150 is a baseline result and I would be happy with it in the context of the birch not being our big play imo. Obv the bigger the better but I thinkwe may need to be a bit more realistic before we get confirmation. I've been burnt too many times as I'm sure some have here. Anyway I 'd prefer to be realistic (150) and dream (500+) at the sametime Cheers :)
