Luna3 is not a wing I would choose for big XC. It wouldn't be a horrible pick, but it felt much more like a very advanced all-rounder to me. And, if I'm gonna fly an advanced wing on a long XC, there are more specialized options. Sure it's fast, but that's not high on my list when I am flying for hundreds of miles. I would pick something less sporty.
Do you have experience with other options? I am try to find my perfekt XC wing and think about the Dudek Hadron 3, Niviuk Kougar 3, Ozone Sirocco 3. Wings Like the Warp or the ViperXC are a step to high. I am searching for effiency in the first place and i don't need a agile wing.
I have 3 years experience in XC flights and in 2023 i flew ~70 hours. I had my SIV training after my check flights. I am from Germany and we must make a license to fly paramotor. ☺️
You are not the first person with this advice, but i fly a Dudek Universal 1.1 since my first launch and the step to the viperxc is gigantic. My Problem ist: I cannot test ozone wings, but i can test Dudek, niviuk and itv Wings in july.
