I agree with Sk8man that the Angler Diaries are not much more than a sampling of a group of anglers on the lakes. It is a great bit of information, it just does not represent ALL the anglers on the lakes.
Just as an example, a few years ago I concentrated on LL Salmon because we had a banner year for them. My report would have shown lots of Salmon, little or no Browns, Rainbows or Lake Trout. It plus others like me who target a flourishing species, will skew the diary numbers an enormous amount given the sample size. The following year I was lucky if I could find very, very few Salmon, so I switched to a different species to target. Since I was targeting non Salmon species my previously huge Salmon report went to near zero. That would be an under representation of Salmon just because I chose not to specialize on them. I am sure there were Salmon out there, they would not be making it to my diary.
Back to the original topic of this post, we need to give a boom or bust a few years to truly tell us how we may want to adjust stocking and take limits. Mother nature deals the cards...we can aid the processes through policy. I doubt we can force too much of a quick change in the balances, I think our policy role is to control the damage we can inflict on that balance of nature rather than to try to fully control the actual balances that exist year to year.
(But if you wanted my opinion 2 bows and 2 browns would work just fine)
