Looks like I might have to build my own, any suggestios, I am shooting a A&H takedownm with aluminum riser.
I have read a little on these. I have heard you do a T sight, or I beam. So your riser will need to be a bit wider.. not much and you do the riser right in the middle of the window.
The only problem with that, that I see, is you really have to learn how to aim and shoot it since the string has to be in the middle also.
I will see what I can find.. sounds interesting!
Another option if limb tiller allows would be flipping the bow --- used to be a picture on http://www.archeryhistory.com/recurves/recurves.htm
