For a 70" long bow you'll need the tallest blind you can get. Double Bull makes one, the size of the Matrix, but taller -specifically for bow hunting. It'll cost you though. You can probably check out the dimensions on their website.
It's listed as an option under Matrix, called the Recurve C/H - 74" center height instead of 67". Good luck.
Thanks, Chisler. Much appreciated.<br><br>Frank<br>
<P>I have one made by ameristep called big house that is 78" tall. Have no trouble shooting 68" longbow out of. Shot a turkey whith two people sitting in the blind.</P>
Thanks, kstout. I'm still doing the thought processes and awaiting extra funds and your information will aid the process. <br>Frank <br>
