Gonna put in my ballast system this spring and have 6 sacs to choose from. I have 2 side sacs @ 260 each, 2 V drive sacs @ 400 each, and 2 L shaped surf sacs @ 700 each. Plan to put 2 bags in front (heavier) and 2 sacs in the back (lighter) I would have no fitting issues putting the surf sacs up front if needed. I tested last fall with the 400 sacs up front and 260's in the back. The wake was decent and clean. I know its best to get out and test, but any thoughts on having the 700's up front and the 400's in the back? Too much weight for a 22' Cobalt? Thoughts? Here is a pic with 400's up front and 260's in the rear with slight trim up @ 21mph.
