I had one BB&O, next to one BOO. Each topped once. The BB&O grew like a haze, very friendly. The BOO influence was unmistakeable, so smells and taste sweet orange, maybe blossom-like, compared to BOO that is straight-up orange zest/oil. I would encourage topping once, she spreads nicely and took nutes no problems. Effects, nice laid-back harmony, not much lock on average use. Although hit her hard, she'll sit you down a bit
. I find myself grabbing BB&O a bit more than BOO during the daytime. Both are great. Hope that helps, hope you find a keeper. I only ran this one pheno, so far.
