Pen dogs vs. Woods dogs

I was wanting to give a shot at making one of my young leopards a competition dog....but I don't want to lose out on a potentially good woods dog either. Thing is, I hunt year round pretty much with exception of summer. I'd realistically only make it to one or two pen competitions a year. I could work said dog in a pen for practice all year though. I just don't know. I guess I just wanted to know if anyone's ever hunted a dog in the woods year round and then used that same dog in any competitions. I guess what it boils down to is that it really is a 'one or the other' kinda deal. Thanks for the insight given so far...I look forward to reading anyone else's insight as well. Thanks y'all.
