I haven't looked up the Perone hive. I also have TBH's and Lang's. I have been thinking about building a long hive using Lang frames. Haven't decided on supers or just longer hive, leaning toward the super. Good luck Blanc
My tbh is 4 ft long and has good space but they build so quickly I have to get in them quite often and the Perone will give them a lot more space and plus I like the concept of it. There are some nice videos of the Perone.
