The bow sac helps bring the bow down and add length to the wave. Best wave for your 22v would be custom enzo type sacs, built to fill your locker and under the seats running forward. Last time I did the math you could fit like 1600 or so on each side. Filling and stacking sacs sucks. So if you have the cash go custom sacs from fly high. Check out wakemakers.com or shop.maxwake.com. I personally buy a bunch from maxwake, because he has factory seconds and used for less $. Some people don't run bow sac, but I think it's important. It won't fill all the way, maybe 450-500 pounds.
As for surf boards that is a totally different topic. It's actually been discussed to death on this forum
Boards are like boats, people have their favorites and are very loyal. I personally like and ride custom shred stixx boards. I personally don't like any boards that are made by wakeboard companies. There are a lot that are hand made and you can get customized to you.
