Yeah tartine. It's a tricky one. I think there's been so much gear come out with manufacturers doing updates on gear that then becomes not reverse compatible with previous versions, not to mention foil board track placement and how it works with some manufacturers and not with others. If you gave me that as a project, it would be a bit of a nightmare. I'd almost say the best way is to get on here and propose what you intend to buy and ask if others have experience with the combo you're thinking about getting. The other thing is some foilers will find combos great and others might not. It can be pretty subjective.
Post some combos up and ask the group what they think.

One of the shops with a YT channel were threatening to list all the foils…

Closest I found is (another forum…🤐)

Thanks for offering your help, I will certainly ask when I want to upgrade my setup.

The thing is I already starting creating gathering data in a big spreadsheet for before buying a board, and then I thought that it could be an idea to create a sort of app that for everyone.

Just checking before it does not already exist and if people actually care too.

Would it be great to quickly know the weight of any part ?

You want to create an app for what? Every few months someone comes along and tries to create a data base or app suggestion. You can't take the data from a wing and incorporate it into some data driven findings alone.

I think you can create an agent/project within any AI on a newer LLM with specific instructions and you’ll find what you want.
Just scrapes reddit, yt, other forums, etc.
Should really be able to cover most of your needs.

The main problem is everyone has a different level of skill and desire for what they want to accomplish. What I like is different to most other people so demo is the only way to go. Shops and brand reps like Stand up shop in Fremantle are awesome in giving out demo gear for you to try. That is the best way to find the perfect setup for you is to ride it. I have wasted a lot of money listening to other people’s views on foils and wings.

I can only agree with the common advices about, start by taking lessons, befriend with a local shop and riders, go when wind is 20 knots-ish and no chop, try stuff, do not go alone, etc.

But then you are in a place with barely no shop shop around, no other riders where/when you go, and not much of a kite or sail background (and an finite budget).

What is left is mostly influencers' s enthusiastic videos/podcast and forum like this one where people keep questioning each other objectivity (which I am tempted to find healthy).

I found on on a thread that a guy complained to discover that a high tier board they ordered was way heavier than expected. This is objective data that people can make available to each other, does not involve human or AI bias , could help you filter out a lot of product when you have to pick one.

Then if you gather data of people about their gear, (what they find useful to share) then you know what they mostly did not sell after the first session. It is not the best reference but that look like a better starting point that the current statu quo.

And that tells you about the market (including second hand) and what is compatible with what easily.

Tha may free up room for more involved threads here?

But if 90% of people around have a gang and a friendly local shop and opportunities to test before buying then, fair enough, such wiki/DB is not justified.
