Yep 150s, I thought I would need the 250s for my 57 @ 29 bows but they were too stiff, cut to 30"s with 100 grain insert and 125 heads. So I sold all the 150s I had and now I have a doz 250's that are too stiff, gonna try and get some 150's(again) cut to 29.5 50 grain insert and 125 heads- that outta do it! I draw 29 and sometimes a little more out of two shawnees both about 57 at 29. My finished 250s weighed in at 610 grains and I'm sure if I loaded the front even more I could make em work but I'd rather not go any higher in total arrow weight, I like shooting a 29.5-30 inch arrow, maintain good foc, good grains per pound of draw and a reasonable speed. Good luck!
