A little arrow help please

[LongStick64]

I have a Hill Cheetah 51@31 and I draw 27". I'd like to shoot Wood arrows but not sure of what spine, I'll be using 160 tips.

Thanks in advance

40-45 or 45-50 cut to 28"

You'll be pulling about 43/44# at 27".  IF you cut your arrows to 28" and want to use 160 gr points try a spine range of 50/55#.
