A good point on the draw length, here is what I have found; when I made bows for people, one thing I noticed is it is a normal reaction for a person looking at a bow you handed to them is to immediately jerk the string back like they are shooting the bow, it is a guy thing. This is OK for a glass lam bow but can be the death of a self bow, particularly if the person person pulling the string back is a knuckle dragger.
If you send a bow to a non archer it will be something they will want to show to their friends who in turn will draw the bow before you can blink an eye.
Adding a degree of durability to the bow by tillering the bow to 30" wouldn't be a bad idea.
I replaced a number of the bows that I sent out when they failed, bows I could have shot for 10 years without a problem, I always wondered how they were treated after they left my shop but I had a no questions asked replacement policy.
I started sending out a care and feeding instruction sheet with bows to let the owner know that their bow was custom made for them and them alone and only people with a similar draw length or less could draw the bow.
I have also posted a thread or two about selfbow etiquette on other sites and found that 95% of the trad guys out the had no idea about the dangers of overdrawing a selfbow. I put in my thread to state your draw length and ask permission to draw a selfbow from the owner before you did.
