Anybody using the Optimus riser from Johns custom archery or the Dryad Mountain Hunter?

I am thinking about either of these in 19" length with a set of 40# medium limbs for a 62" bow. Mainly hunting with a few local 3-D shoots tossed in.

I can't speak of the dryad but John F Mosier aka Breathn is an archery legend of sorts. Dude builds some.of the baddest compound bows out there(frankenbows of course). Also an awesome string builder. He builds all my strings for my shop. As for his trad risers...have heard absolutely nothing negative about them on social media. Those that have them love them. And John harvests animals with his every year. I'd certainly not hesitate to purchase one from him.
