Jeff,
not sure how many brookies there are left, but they are good looking fish. I would strongly reccommend the weed bed at this time of year, as it's shallow they will tend to hide there, as it's warmer. However the corner of the arm mentioned is probably my favourite place just about the rest of the year, so always worth a go.
I do agree with the size issue. Although i'm not fussed by that personally; they produce a great fight and are generally very well conditioned, but i don't eat them. If i did it would be for a starter.
Robster- not my preferred style of drifting, but the fish found in there will generally be spread out and solitary, it just allows you to cover more water in a short space of time, and these fish are well worth hooking. It isn't trolling, you use wind power, as in any other type of drifting.
