This 100%. I think both gold and silver will do well in the long term, but silver has so much more upward potential. If silver doubles from $16 and change today it'll be between $32-34/oz. Gold will have to break it's all time high to double from where it is today to $2300 or so. As much as I like gold, silver is the place to be right now. Once the gold/silver ratio starts trending the opposite way, trade some of that silver for the gold.
That being said, my focus on stacking is 100:1 silver:gold right now.
