Apollo with a 80 cm fin to Remi

An 100kg apollo happy user is thinking about a 80 cm fin to put into apollo during light air racing.. RS6 12.5 sometimes is not enough to get going and a powerfull fin could be an interesting option I believe.

Would R19 medium 80 cm, rake + 8cm would fit this combo? Remi would you please follow up? Time ago you reccomend 75cm as a maxium. Why not to go for 80 cm during fun racing when the middle-european summer starts. You should have some experience...

Any valuable comments would be welcome.

Kind regards

Tomi
