I’m running mine the Edd way, but I can see the benefit of a single page if you’re not needing to do normal DECO/deep & long, and lost gas plans. If I need to write a book or bigger plan I use my wetnotes.
Edd setup my Petrel 1 mounted on the triple slate and I agree it is a bit bulky and I never needed the extra space... maybe I'll try this with my Perdix AI which I've left with just bungees and no slate... I dislike wet notes
