Hmmmm??? Im confused. Your obviously inexperienced and you asked a question wanting an experienced answer. And you got some great answers and had two good options to choose from,but didn't take the advice of any. So why even ask if your not gonna listen to over a hundred years combined experience from guys who have been doing this a long time and have been there done that.
To even get a chance at getting that bow to 25" now you need to thin the handle down to make it bend in the handle and heat up the handle area and deflex it. And that's still pushing it a lil past the limits,especially for a selfbow. Sinewing it wood give it that chance tho even after thinning the handle and deflexing it. Good luck.
Careful in deflexing a handle area. If your not careful and keep everything lined up straight you'll throw your tips and centerline out and the string will be off the handle.
