Never had Piton, but there's something about beers like that brewed in tropical locales that you just can't beat.
They are pretty secretive on their website, though they do say that they use corn. So I'd build a recipe with Pilsner malt and a small amount of corn. Probably 5-10%.
For hops, most German noble hops will give you some degree of floral character and maybe a bit of citrus. Especially added later in the boil. One variety I like well that has some lemon rind character but is overall quite noble-esque is Loral.
Keeping it simple for yeast, 34/70 no question. If you can control your temperature, ferment between 55 and 58F, if you can't, just focus on keeping it cool towards the beginning of fermentation. I've used it at ale temps and like it a lot, but I find that it makes a noticeably drier beer fermented cool. And that's what I assume the target beer you're going for is.
Don't forget to let it lager in the bottle or keg or fermenter for at least 3-4 weeks but preferably 5.
Good luck and report back!
