thank you so much for your kind responses. I've read the old posts by Krister, very interesting argumentations. Seems like on the Apollo I will achieve the super early planing I'm looking for, as the non-planing side of the practice is not a priority for me (so, no need for a raceboard or a Serenity.. but I'm sure they're both worth a test ;-)).
One last question: I will use the stock fin for the ultra light conditions (80% of the time), but I guess a smaller fin is required for the top end. I've never experimented with fins, so I need a suggestion: what Deboichet design suits better my needs and weight? Maybe a 70 R17 (reading other topics)?
Thanks in advance.
