Smudger,
I am in Shrewsbury too and the Reabrook all the way up from its confluence with the Severn in the town hold lovely ladies.
Also Welsh dee at Llangollen is superb.
The Reabrook is £30 to join the Shrops Angling Association - from Total Angling in Battlefeild. 7ft 3wt or smaller/lighter.
From 2nd Jan you can join the now amalgamated Maellor and Llangollen clubs - both have websites but the Llangollen one is better. Or day tickets from hardware store in the town. £70 country membership. 8'6" 3wt or 9' 4wt.
Ludlow also has some free water on the Teme between the bridges from the Horshoe Weir up to the Ludford Bridge.8'6" 3wt or 9' 4wt.
Plenty to go at - but as others I have spoken to seem to be having the same problem - the temperature needs to drop a good bit before you can avoid the plentiful head of brownies to be found on all these waters.
Feel free to pm if I can be of any more help.
Clabedoo
(I know its pelled wrong)
