Jeff Rapps is one of the most reputable vendors and distributor of fish so if he says they are monos, they are monos. I'm not sure about a collection point or river but they're from Putumayo, Colombia. $20 or $17.50 if you buy 4 or more for a pure mono, I think that's a steal! So you should grab one more lol. They're probably just gonna look like any other pure monos which they're badass. A lot of the stuff you see at lfs are hybrids. I've seen a lot of peru and lake diamante monos but I don't think I've seen colombians. So it would be nice to have members who owns colombian monos to post up some pics.
