I own three WW one-piece recurves, so I'm going to be a bit biased. Two are 64" and one is 66". These are the best-shooting bows I've every shot, super-easy to tune off the shelf, fast (well, fast enough), just a real stable shooting platform. I'd say the bows have somewhat of a target vibe to them. I have a 30" draw length, and the past few years I've really been moving toward longer bows. Many, but not all 60" bows I've shot have either stacked, or to some extend 'tightened-up' toward the end of the draw cycle, I'm finding longer bows just work a bit better for me, more forgiving, and I'm just more accurate, with scores on the standard 14-target field range having a marked improvement. The only downside to my Mentors is they are a bit challenging to keep the noise level down, but not unreasonably so. The fact that it's a beautiful bow doesn't hurt either!
Of my three bows one has a bubinga riser, one has a Bolivian rosewood riser, and one has a zebra riser. With respect to mass weight, from heaviest to lightest is bubinga, B rosewood, and zebra. My zebra bow weight about as much as a 1970s super kodiak, whereas the bubinga riser bow is a heavy-weight! The weight certainly adds stability, but I do like the zebra bow for carrying around (because when hunting I'll be carrying a bow more than shooting it). I don't thing there's a right choice here...
None of my bows have veneers on the limbs. For core limb wood, I have one with osage, one with red elm, and one with yew. Of those three woods, osage has the highest density, and I do notice a tad more vibration from the osage-limbed bow. However, that's also the bow with the zebra riser, so is the extra vibration due to the heavier osage limbs? Or is it due to the over-all lower mass weight of the entire bow? Not sure... From a performace-standpoint, all three bows seem to perform the same, just a tad more vibration from the osage. The bow shoots great, the slight vibration issue is just an observation, the osage limbs shoot just as good as the other bows. If I could do it again, I'd actually get my bows with bamboo limbs and BLACK GLASS. If I was to get clear glass, you simply can't beat the looks of that yew, just beautiful. I'll probably be ordering another bow soon, it'll be a 66" version. I'm actually considering a stealth, something not quite as beautiful to take into the mtns, maybe even camo-paint the whole thing!
I've looked hard at the one-piece Silvertip, very nice bow, but unfortunately with my long draw length the 60" amo is a deal-breaker, unless I ever get a chance to shoot one and assess it's suitability with a 30" draw.
