Thanx MadMax!
Good Ash actually is much easier for me to obtain than bamboo or hickory. It's the local stuff, not so bamboo
And its more convenient to work with than boo also, glueing also better, less work. I do not know how good it actually is but at least I never had one failing.
This one has one sister bow with boo backing tough, little experiment. maybe I'll make a chrono challenge with them.
cheers
