We test drove an F22, looked at Axis, and ended up with a used Supra SA 350. We were coming from a Sanger V215. Compared to the MB B52 the MB has more interior space than the Supra, by about 3 people I would guess. I think you cant go wrong with any of these, but I felt for the same price range for a 2 season supra with 120 hours there was alot more the supra had to offer. Wakesurf wise I have had mine full listed ballast, 11 people, and couldn't get the starboard side wave clean in a deep lake.. Port was great. So I bought a Nauticurl and that should solve that issue. $200 instead of buying a year or two newer boat that hasn't depreciated as much was our tactic for the wakesurf wave. Wakeboard wake is pretty massive on the SA, but with no ballast would be fine for kids, its pretty mellow for learning. The supra does get low up front when loaded with ballast and people, they fixed this with the 16 redesign. You won't have that issue with the MB B52. I didn't want a B52 as it's pretty gigantic to store and clean in our storage situation, but if you need more room than 10 people comfortably I'd look elsewhere than the SA. My only complaint with the F22 was it felt like you sit pretty high in it, where the gunnels were more mid back than up around your shoulders. The ballast system on the MB is sweet for sure. Fills fast and the SurfAssist built in is nice once they fixed the way the swim deck covers that. Some older versions the surf plates stuck out past the swim deck which I could see being an issue when you get 6 kids playing on there and they are climbing up from the side, which is our situation with kids and boating right now. I think the MB would surf better from what i've heard and seen as stated above, but the styling of the SA can't be beat IMO. There are some screwy things that took getting used to of course but to have navigation for every body of water in the US on the touchscreen, programmable graphics, 15 rider presets, heated drivers seat, trash can, swivel tower speakers etc etc etc the features of the SA put it in a higher category of boat, and for less than a new MB. Again we found a really quality used Supra in new condition.
They both pull out of the water nicely loaded with ballast, mine has the high altitude prop so it pulls great but top speed cruising at 3900rpm is 30 mph. Both have nice trailers, stereos from the factory etc. It's a great time to get into a few year old boat, they have come a long way! Youhave a great problem, we were there a year ago and are stoked on our upgrade.
