Have you used one for a period of time?
I love cockers...and I know how to work them...but, if you dont...I would think that potentially...you may be dissapointed going from your Angel, to a Cocker...especially a basic one...if it is a DC2 (around £250 ish) then great, but...you still might have issues with it.
If you have around £250 to spend...consider trying something like an Ego as well and see what you think...much easier to get along with than cockers.
I dont particularily like Angels, so consider that when reading the above.
I do like cockers and I love my Ego.
Dont buy an ANS, they are Fockers (replica cockers) and are ****e, to be honest.
