NSP Front wings selection help needed

Hi All,
Just starting to learn to wing foil and tow foil. Not had many oppertunities with the wing but can now tow foil continious no problems.
Currently got a massive NSP 2500 front wing and looking for the next size down. Reading on the NSP surfboards site one area says the Gull wings are perfect for beginners then the table at the bottom says the gull wing series is for intermediate to advanced.
So totally confused which way to go. They have good deals on with NSP at the moment, maybe they are not so popular any more. Hopefully still ok for a learner.
So looking at a 1720 Gull wing or a 2000 “Allround” wing which is not actually even listed on there table.
Any advice appreciated.
Cheers.
