Yes, I use them on two of my bows. Here are the specs - Both set-ups use the same length arrows : 1535 shafts cut to 28.75", I use 3fletch and 4 fletch arrows as well as flu flu's-
Martin X-200 (Recurve cut to center.... I think), 43# @ 27.5", i use 145 gr field tips and 142 gr B/H's;
Martin L-100 (Mild R/D - is a Ragim LB made for Martin, +1/8 off center....I think thats the way you say it) 45# @27.5, I use 155 gr field tips and B/H's.
***I do not shoot off the shelf - I use a Bear rest trimmed down, and set up real low. I love the 600 spine, I was over spined for several months. Hope this helps.
