I agree with Sarbar - if you like it, and it works, there's no reason to change. You will end up carrying 25-30 pounds, depending on how big an eater you are, the type of cooking you do, and how much water you have to carry at any one time.

You can go lighter; for three-season weekends in the east, I usually carry 19-21 pounds, including food and a quart of water; in colder weather (lows around freezing), that rises by about 3 pounds for clothing and some extra food. However, reducing your weight may require you to change how you do things: replacing a spacious 2-person tent with much tighter solo tent, using freeze-dried meals instead of some fresh ingredients, or not changing clothes all weekend. Only you can decide what kind of compromises you're willing to make for a lighter load.
