Ill give a small beta on each park.
BV had four features at the low flows. The top hole was sticky and I was smackin rocks when trying to loop "not good at loops". Still was fun to bounce around in. The second wave down was fairly mellow and great for spins. A good wave for beginners. The third wave was very mellow, good for newbies just learning to surf. The fourth wave was fast, big, and tons of fun. I was watchin guys throw big ol blunts and cartwheels.
Salida had four features but the top and bottom ones Im not going to talk about, no fun at all. The second hole down is great. Not as sticky as BV's top hole but deep enough to loop. The third feature is a solid wave waiting for somebody to spin or cartwheel. Its also fairly friendly to beginners.
Both are good parks but BV has more options and the LoDo wave is where its at.
