I'd really like to see a bowyer's perspective on these two though. I suspect the Guadua would make for a softer and more readily dented outer surface, ...but few of us walk on our bows or swing them at stone pinatas. From what I read, the right glue should actually work better with the Guadua than with the Moso. I think this calls for a side-by-side comparrison by a bamboo bowyer!
