At the moment, my mix in dollar terms is about 33% gold, 66% silver. Ideally, I would like to balance this to a 50/50 split based on fiat valuation, so have been snapping up some gold here and there... which is hard, when silver is at such a tempting price.
I tend to think you need some gold in the mix, simply for stability/wealth preservation. To me, whilst I firmly believe silver will have its day in the sunlight, the question becomes "when" - it's looking more likely as every day passes, but if SHTF (and I believe it will), having something that may be more widely recognized (gold) may prove useful.
