Last weekend I finally installed all my ballast bags , the new prop on, and got the wake tweaked so I figured I'd post how my set up turned out.
Here's the end result:
Wakeboarding Wake Ballast set up for my A20 is the 800lbs of factory hard tanks, 2x 600lbs Sumo sacs in the rear lockers, the 950lbs sumo arrow sac under the bow and a 500lbs fatsac on top of the bow seat, wedge up.
I was going about 22.4 mph with 3 people in the boat and it's curling right around 70' back, this thing is a monster!

Surf Ballast set up is the surf side hard tank and surf side 600lbs Sumo sac in the rear full, the 950lbs sumo arrow sac in the Bow 3/4 full, 500lbs fatsac on top of the rear surf side bench seat, and wedge down. I had two people in the boat and was cruising at about 11.5, I'm still playing around with the weight for surfing and few more people in the boat couldn't hurt but it was still a great surf wave.
I ended up going with Johnny’s suggestion and getting all sumo sacs, and I'm glad I did.

I've never had any of the flyhighs bags so I can't compare the two but the Sumos fit in the rear compartments and under the bow perfectly, no real pressure point to worry about that I can see and with the 600s there is no need to re-enforce anything (which is something I didn't want to mess with). Also I really like the "Quick Link Valve" fixture on the Sumos, it's awesome for burping the bags and since the ports are all 1" I was able to up the size of the hose that gravity drains the rear sacs to hard tanks on my '12 from 3/4" to 1" very easily which really seems to help drain faster, I don't have to wait for the sac to catch up to the pump like I've heard some people complain about. Here's the thread on it
viewtopic.php?f=14&t=1688&start=10I have the AR335 engine and went with the Acme 1235 prop, it has zero trouble getting the boat up and going with the almost 3500lbs of sacs plus a few people, I'm super happy with its fuel economy, and didn't seem to lose too much top end either.
Thanks again to everyone for their advice much appreciated!
