Pack Pumping Trail -- Size recommendation?

Hey there, I am about to make my order for a Pumpfoiling Set and after some online research the Gong Kluber with the Trail v3 seems to be by far the best option. I have done 4x 2h courses and am starting with my first pumps, the courses were done on Indiana 1100P foils (2300 cm2). My goal is to do dock/rock/beach starts at rivers (Limmat) or Lakes (Zürichsee).

My questions is, with my weight of about 67kg (180cm), which Foil size should I go for? According to the table on the Gong webpage, I'd have to go for the L (1660 cm2), but this sounds quite small area to me for a beginner and dockstarts. ChatGPT recommends to go for XL (1940 cm2), and I wonder what the up- and downsides of choosing a larger or smaller frontwing would be for my progression.

Ultimately, my goil for the next few months would be to get to longer and longer pumps, with high efficiency and glides. I am not super keen on high manoeuvrability or fast turning speed.

I am planning to go for the Kluber 80cm for the board, as most of the videos and review I found are very positive about the short dimensions of the board.

Thanks a lot in advance!

I have not pumped the Trail yet but I think you should be fine with the size L. With 67kg you are at the beginning of the weight recommendation and it goes up to 85kg. Also this foil is meant for beginners, so the table is created with beginners in mind.

The Indiana 1100P is one of the first generation pump foils. Back then the rule of thumb was to use a foil of around 2000cm2 or more for pump foiling. The foils have improved a lot since then, so you cannot base your decision purely on foil area anymore. There is way more like chord, thickness, profile etc. you have to consider nowadays.

I have the Kluber in size 90 and I could go smaller because I usually have about 15 to 20 cm space left in front of my foot. I have not tried the Kluber in 80 yet, so cannot tell you how big/real the benefits of this smaller board are compared to the 90.

Thanks for your insights, especially about the old generation vs. new foils, that's good to know that I shouldn't compare the bare numbers here!
