Had a few of those in my time too, glad all you had were some scrapes......and yes some speed on drops is your friend.
FWIW, i ride my XC rig on some of the same trails as you and it has a 66* HTA and never feels lazy, slacked or enduro bro. Nimble to me means twitchy, and takes too much energy/focus to keep the bike under control rather than just plowing ahead and having fun. I've spent the last 2-3 years riding bikes with 64-66* HTA, including 29ers, and i'll never go back to twitchy.
You're welcome to take my bike for a spin the next time im over there.
