For rough shooting and beating and esp so if times going to be more limited as others have said LAB all day long..
A lab will do almost everything reasonably well from deer, to flushing birds to water work, pigeon hides, won't get cold either in water or hangingvsitting on a peg/hide. And esp excell at being a pet
A lab won't needless bash cover the way a spaniel will but If ur lab wont hit cover with scent present ur labs not very good. Most of the shoots in my area the beating teams are mainly labs
Yes other breeds may do something better than a lab, say a spaniel flushing but there weaker points will be far weaker than a labs..
They're is no wonder breed out there that does everything well, every bred will have strong and weak points, u make ur life easy and set urself up to have a really deceent dog by choosing a breed that most of its strong points are wot u use the dog for
Personally i think an hpr is a waste of a decent breed if ur not using it to point, using a well bred driven hpr in a beating line is like using a ferrari to do the school run, just a pita really, yes they can do it but not really that suited either for handler or the dog.
