Kaholo 12.6 leash attachment

Finished with the Kaholo 12.6 strip deck but two finishing touches remain: leash attachment and adding the deck plate.  How and where to apply the leash attachment. I bought the one sold by CLC. Screws or epoxy? Second question similar: how to insert the deck plate. My husband says to use screws but I contend that thickened epoxy will be strong enough and will look better. Any opinions?  Thanks, Denise
