You can't beat metal for strength, stability and adjust-ability, The Gen 3 mini I'm shooting has added 3.5 oz.lead in lower part of the riser for more stability. So far mid 30 degree hunting and have not had a problem at all with it being too cold, I don't hold the bow 100% of the time once on stand and do spend too much time walking around before taking a stand so I do hold it plenty. I do have a Jager grip of plastic and rubber. And have already being contemplating making a grip of Styrofoam if it gets to be a problem, not something I'm planning on producing but anyone with a pocket knife should be able to make one. I still love pretty woods in a bow and will continue to hunt with both. But if I was only to have one riser and never to have a choice it would be metal, It will last a like time with no exceptions, other than if your wife decides to throw it in the fire along with the rest of your hunting gear...
