Nothing wrong with learning by making your own mistakes
Not listening to others is also your choice
I am in the same camp as Corvus - only the finest materials and techniques are used when it comes to a horn bow. A wooden bow that only takes a few hours to make is different. A good hornbow will have many hours in it and I don't like wasting my time haha.
You may have one person whom you 1000% trust but I preferred to get my knowledge through the consensus of the majority. I would suggest that all these 'tricks' have been tried before and disguarded for whatever reason - there is nothing new under the sun
When a bow type (composite) has been made and worked on for easily a 1000+ years I am humble enough to realize that the consensus is probably right
If you aren't bothered with tradition I would use EA40. Mixed 2:1 and cured at 40 - 50 degs.
