I'm thinking about getting more into SUP foiling, and my current gear isn't cutting it. I've tried on my custom FSM 4'10" 98L but i really can't stand up paddle that thing. I'm about 90 kgs. Both these boards could serve multiple purposes: the Armstrong for SUP foiling as well as light wind winging; the Hypernut for SUP foiling and regular SUPing (i currently own and love the Hypernut 7'10" but it's getting old and beat up). I think the Armstrong is probably the better fit as I use all Armstrong foils and think its mast track placement is better than the Hypernut (which looks too far back). BUT...I can get the Hypernut for half the cost of the Armie. I suspect the Hypernut, even with its less volume, would be more stable in chop, and stability is very important to me. Glassy conditions tend to be rare around my parts, and I'd tend to ride these in smaller waves (under 4') as anything bigger I'll usually just basic SUP.
If anyone has advice on these, would greatly appreciate it.
I have the 6'4 armstrong and had the 8'0 hyper nut foil. I am about 85kgs. I learned to sup foil waves with the starboard before moving to the armstrong. I ride armstrong foils too and they work fine on the starboards. I have had no issues there. Moving to the 6'4 from the 8'0 was definitely a change. With the longer starboard, I did not have to think about paddling. It went pretty straight. With the armstrong, I had to learn to paddle it straight with better technique. I still paddle an arc to get waves with it most of the time. It was wobbly at first but I my control and balance got better the more I used it. about half a dozen sessions and i was good. The armstrong is also my primary wing board at the moment while deciding what smaller wing board i want to go with.
Now I also have the starboard hyper foil in 7'2 for choppy conditions. I found one really cheap and have used it in choppy conditions. It is stable and rides fine. You are in Jupiter if I remember. Jupiter kite has one for 999 at the moment. might be better with sales now. I have actually used this board several times to back track wing foiling to practice and get better with foot switches and riding switch. For light wind it was great mowing the lawn. I could practically stand with my feet parallel while winging it. Nice and stable in that respect before doing it on the smaller armstrong. I know this will not allow for normal supping but it might make your foiling suping more enjoyable. And it is cheaper than the armstrong.
Just coming off a 7'4" Hypernut (older Tuttle version). You can look up some of my older posts; I'm now on a Kalama E3 DW
Long story short the Hypernut is stable and good for SUP. But that wide bottom does not release anywhere near as easy as newer foil bottom designs. If you're actually going to SUP it then it's an ok trade. I've found I'm never grabbing it for that. If I'm SUPing I'm foiling (unless it's flat water). Going back to it from my newer board recently the first thing I did after getting back to the house was list it for sale..
Id recommend keeping your old one for flat sup; and grabbing a newer design for SUP/DW/Light Wing.
