HI Chad
Bit slow to this one, sorry
This time of year, the fish are probably sipping spinners, size 18 spent orange spinner will be the biz
if that fails to generate any interest then i would bet all my gear they are taking tiny buzzers, size 24/26 black or yellow.
Very hard to keep them on, but lots of fun getting loads of takes
Give both methods a try, the spinners will pick you up the better size fish.
If you are fishing Inverurie, try the urie at this time of year especially the upper end with the orange spinners, some great fish even since they have built the housing estate
which has changed the attitude of the river quite a bit.
Have fun
Sandy
