Guys,
I need a little help.  I recently got a 68" Adirondack Deluxe.  I love it and it shoots great.  I need to get some arrows and am not sure of what spine i need.  It is 50# @ 28" not cut to center.  I draw around 27 1/2".  I like the carbon express heritage shafts but have been thinking about aluminum as well(a little easier on the wallet).  It has a dacron string on it but i am thinking about getting a padded loop 10 or 12 strand fast flight string for it.  Any input would be greatly appreciated.
Thanks!
Nate

try some port orford cedar shafts from kustom king  maybe 65-70 spine  they work great for me    5

Nate, I plugged in some of your info at Stu Millers spine calculator and came up with a 1913 aluminum arrow @28.5" with 125 grs. roughly at 190 fps. and 14.8 foc. That was with the B50 string.  

thanks guys

My Shrew likes Carbon Express 150's with 50 grn brass inserts and 160 grn broadheads. My draw length is close to yours. They are a little over 28" long. They sure seem to be a tough arrow.

50-55 cedars with 125 or 145 upfront would be deadly quiet and cheap eough. Plus I think cedar shafts are the coolest thing since........? cedar shafts? I would try all 3 materials and decide what style you prefer. Alum., carbon and wood
