Deerhunter,
The solution is two-fold:  a.  Don't shoot the grass 
 
 - b. Try the weed whacker brush knot that was up a couple weeks ago 
 
!  Also, a garden rake to help find the arrows under the grass! 
 
!  I do have to reweigh my arrows as I shorten some, but I think they will hit 10 gpp.  I do like a heavier arrow for hunting, 500 gr plus off my 45# - 50# bows.  
Take care with the back injury and do keep us posted!  Those are serious, and get at least one second opinion!  I crashed on a jump in '78, and the doctor promised me a permanently sore back! He was right!  But our battalion surgeon, an orthopedic specialist, told me not to get cut on until it was a last resort.
