If you will be following a dog all day a pound is a lot of extra weight to carry. Especially if there are hills. It is also extra weight to mount and swing when you flush game. Think about all you will be carrying for a day of hunting. Gun, powder, shot, food, water, cel phone, compass, map, car keys, wallet/ID, license, game bag, knife, rudimentary first aid kit, and whatever else you may deem necessary. And if there is a dog you may also need food and water for it. As to balance and handling qualities? You really don't know without handling both guns. Try to find them to evaluate in person.
I have a good assortment of sxs unmentionables. The ones that weigh more than 7 pounds usually only go to the range or hunting from blinds/boats.
I would suggest trying to find them used, not abused. You might be able to afford both.
