I've never heard of the Isonic 122 Wide and I've had several Isonic 122's (one of my all time favorite boards).
Are you sure you are not talking about the Isonic 117 Wide (I like this one almost even better).
As far as the Formula Experience, your sails are very small for a board this wide.
Normally the class sail size for formula experience is 8.5 m2.
You might plane slightly earlier with the FE board, and your 7.5 , but your smaller sails would not be appropriate for the kinda heavy ASA skinned Formula Experience.
If you liked the Isonic 122 you had before, might be best to go with a know/proven board for you.
7.5m2 is still quite small for the Isonic 122 but I've sailed them with sails all the way down to 4.8 before an they work pretty well and go pretty fast.
