Minimum Amount of TP Scrolls Needed

I hate having my inventory cluttered up with tp scrolls, so I spent a while calculating the tp scrolls that are actually necessary to have. This is what I came up with:
Detlas, Selchar, Almuj, Rymek, Troms, Bucie, Olux, Gelibord, Maex, Lutho, Aldwell. Optional mount enclosure scrolls. Explanations:

From Detlas, you can take the tunnel to Ragni, and you can also take Calo's Airship to Cinfras, where you can take the Juggler's Tavern to Aldorei, Amshord, Thesead, and Rodoroc. From Rodoroc you can get to Thanos via the dwarves trading tunnel. From Thesead you can also get to Eltom using the secret passage. Next scroll: Selchar. From Selchar you can get to (only counting towns here) Llevigar, Nemract (from which you can get to Tempo-Town via the magical obelisk), and Nesaak using the Seaskipper, and Corkus via the C.S.S. Wavebreaker. from Corkus you can go to Kandon-Beda using the hot air balloon. You can also get to the gate of fruma using the seasikpper, which you can then get to Torann through the gate, which has access to the Fruman Underground, which connects Espren, Timasaca, Hyloch, and the Market Square in Aelumia. Almuj, Rymek, Troms, Bucie, Olux, Gelibord, Maex, Lutho and Aldwell don't have any fast travels connected to them, so scrolls are necessary. Forgery is optional. By the way, I'm classifying Tarneves as a mount enclosure, not a town, as I doesn't have all the merchants. Bremminglar, Lusuco, Relos, Maltic, Elkurn, and Lexdale don't have tp scrolls.

 

Realistically, All you need is Detlas and maybe Espren (it's free why not?). Lutho and Aldwell are nice as well
