Hi Nathalie.... I have been pondering this all day.... but I need to know more. So I'll be guessing a bit, If you don't mind
Claimer: I am a proud Sunova Pimp. 100%
I am guessing you are young and athletic, since you are thinking past the "start-up" stage and thinking "advanced" in short order.
1st of all.... whatever you get will suit your husband more than you after the 1st semester.
2nd.... you will be getting another Sunova when you are ready for stage 3.
Start-up on SUP surfing, with no prior experience, has challenges that are usually better learned on a board with a measure of comfort.
Sunova has at least 4 boards that you can consider. Some easier, some harder. I am going to lay out 4 boards and their advantages.
From hardest to easiest overall.
All remarks are aimed at a TOTAL beginner
Speeed - size for size.... the tippiest of the bunch. The lower volume ones for your weight range are pretty narrow for a beginner.... even a light one.
Best paddler, nose makes take-offs super easy, turns best from the tail, so not particularly beginner friendly at first.
I would recommend a 9'2. You could struggle away on an 8'10, but the 9'2 surfs just as good for your purposes.
You will never outgrow the Speeed, but you may outgrow the size. Great in all conditions.... but the narrower ones require skill in chop.
Soul - very straightforward surf SUP with no surprises, moderately stable size for size, Easy paddler, turns from anywhere on the board, will grow with you as you advance, but will not give as much advanced performance as the Speeed or Flow.
I recommend the 8'11 with an eye to the future, but you could go 9'5 to ease your learning curve
Flow - Size for size it is the most stable IMO, paddles with more "yaw" meaning it's hardest to paddle straight of this group. The outline curve that makes it turn easily when paddling, will be a challenge for a beginner paddler.... it is also makes the board super easy to turn from the middle, and that
should help you progress faster. The wider tail adds to overall stability and catches waves super easy. It is fast and responsive on the waves.
It will keep you happy into advanced SUP surfing in small to head high waves.
I recommend the 8'10 Flow, but I wouldn't go any bigger.
"The One" - 9'5 - this is a little known board at the moment. It is the same shape as the 9'5 Surf from last year, but in a new construction. It is the biggest board in the bunch, in all ways. Wider, more volume, thicker rails, generous nose and tail to aid in stability.
"The One" is a great paddler... awesome for flat-water as well. By far, the most stable of this group. Big enough to take the dog for a casual paddle.
It is similar shape to the Soul, with more foam around the edges for extra comfort and ease of use.
The one" surfs great... turns easy and carves well. it is fast and lively... I enjoy this board a lot..... not the same performance of the others in this
group, but enough for years of growth. A great "goto" board when conditions get sloppy. Small to overhead surf.
I recommend the 9'5 for you and your husband.... more numbers than you need, but it will be the easiest to learn on, and the bonus of a flat-water
board as well. See my video from last week.... "

Don't know if this helps, but it may help understand the good points of each.
