It looks like those two companies list mainly fiberglass laminate bows. Sounds like the OP wants something all wood.
He needs to be more specific, “all wood. No fiberglass. Either composite or just one species of wood“ suggests he’s ok with a laminate, even though laminates are not all wood but rather also a significant amount of glue between the laminates.
In the case the Kota and BlackTail bows They use a three layer laminated bamboo core sandwiched between wood veneers of your choice, then covered in a layer of thin fiberglass cloth and clear resin to protect the wood and seal it from moisture changes. It isn’t providing any significant power to the bow and doesn’t seem to diminish the feel of the bow, especially the smooth draw and liveliness of the bamboo core.
It comes down to what he specifically wants.
Does he want wood feel and performance? I used to race on a set of Epoke skis that had a wood core with an opaque fiberglass outer lamination (much like the Bear recurves and long bows). It gave the liveliness and feel of a wood ski, with a lot more durability.
Does he want the look of wood? I used to own a wooden canoe finished with a layer of fiberglass cloth and clear resin. Unlike a traditional wooden canoe it didn’t gain 30 pounds of water over the course of the summer. At the same time it also offered the look and the silence of a wooden canoe.
The Kota and BlackTail bows accomplish both by using minimal glass and clear resin. Bows like the Bear Montana don’t look like wood bows as they use opaque fiberglass laminates on the front and back.
If he wants a bow that is 100% wood and has an exterior finish that doesn’t involve a layer of glass and clear resin, he won’t find it in a production bow.
