Some Hobie dealers may still have a set of the Hobie #122 Super Jib Battens still in stock. If not, I am glad to see that Murrays still carries them as #30-0122.
Both the regular jib battens and the super jib battens are made of fiberglass. The super jib battens are thinner (width and thickness) so they flex more.
With new super/flex jib battens, they will probably need to be shortened so the batten end caps just barely extend past the jib's leech (this will help minimize hang ups, check out the super jib batten leech end caps on the attached picture).
Last fall, on my 84H16, I replaced my Hobie 1987 Blue Prism sails with new Hobie 2020 Tortola sails. I was able to move my previous super jib battens and regular main sail battens over to the new sails with no problem.
Don't forget that adding jib and main halyard grips (#114) will prevent the leech ends of your jib battens from getting caught on the jib and/or main halyards.
On the attached photo, you can also see the placement of my jib halyard grip on the port side of the mast (about where the chartreuse and orange colors meet)
