Ah ok, so you climbed the brutal Pipeline and then rode the gnarlier side of the park (Boulderama). Left of the Pipeline is more rider-friendly for the most part. I cannot ride Sunday morning. Hopefully someone can give you a tour but if not, take a look at the map and follow the marker numbers:

Best direction to ride the trails is a big perimeter loop going Clockwise starting on the grass slope above the parking lot pond. Full loop takes you in order through Markers 13-12-11-10-9-8-7-(6 optional)-4-Devil's Half Acre-1. This will be approximately 6 tough technical miles with 650ft. elevation gain.
New Blue circle trail Chunky Monkey is not on the map but it is an 0.7 mile offshoot from the Red Three Amigos trail (called Roaring Brook on the official map) between Roaring Rocks and the TX Eastern Pipeline. I will work with the new park management to get the map updated. I doubt they will rename the trails to what the mountain bikers call them though, so here's a rough reference to eliminate confusion:
Marker 8 to 7 = New Shoes (on Strava)
Red circle from Roaring Rocks to TX Eastern Pipeline = Three Amigos
Red from TX Eastern Pipeline to Marker 4= Montezuma
White from Marker 4 to Marker 1 through Devil's Half Acre = Boulderama
