pop-products vs fly high sacs

I have an 07 x2 and it likes to be weighted up. I have sacs but it is not plumbed in to the boat. The cost to have it plumbed is almost the same as buying equal amount of weight in pop products bags. I have pop up front and love them because you can get a lot of weight in a little space. What are thoughts on putting all led in the back to keep all my storage as this is only a 20' boat. I store the boat within 100 ft of launch ramp so towing is not an issue. What are some thoughts on this pros and cons???
