If that's what you're thinking mate, go with that. Your dog, your area, land, permission etc. You'll know better than us lot, what will suit you and the conditions you have to work your dog/dogs ?
And if you prefer smooth coats to rough/broken, you'll be increasing the chances of having a litter of all smooths. ?
And before someone wants to 'stone me to death' over my 'coat' reference, I know coat doesn't really make a difference to a dog's actual working ability, but some people, me included, prefer smooths ?
