Awww Clam just had a look at the pics on your profile - gorgeous dog!
Our Labradoodle has actually turned out to be a lot smaller than we expected - he had giant paws when he was a pup so we expected him to be huge. He actually looks about the same size as your cockerpoo (he's pretty much the same colour too). He still has his giant paws now and just looks like a big clown 
I will also say that we (accidentally) ended up with what seems to be the holy grail of 'doodle ownership: A completely non-shedding dog (I shed more than he does!)
This does present its own problems though, because he doesn't shed, the new fur coming through tends to matt up with the existing fur so he needs daily brushing, lots of time at the groomer's and we spend a fortune on leave in conditioner spray to try to manage this.
At the 'lab' end of the scale, the coat is more manageable, but sheds loads. The further towards the 'poodle' end of the scale, typically there will be less shedding, but more grooming is needed.
Gorgeous breed though; playful, sociable, friendly - the perfect addition to our family.
