As I'm still a relative newbie to archery < I've been shooting since late summer last year> I have a question regarding arrow selection.

I have an '09 Martin X-200 50# @ 28". Over drawing about 2" so as far as I can estimate my total draw weight at anchor is around 56# i think. Anyway, my arrows are cut at 29 5/8". Easton's shaft says at 29" I need XX75 2117's and at 30" 2216's @ 50#. If I take it up to 56# it changes to 2216 and 2219.
So... any thoughts on which  would be best or is it just a personal preference since I'm cutting them right in between the proscribed lenghts?

Why cut them down to "perfect" length at all?  I'm in your situation too: my draw weight is usually right at the border of two spines so I can choose either.  This time around, I had the choice between Heritage 150s and 250s.  I went with the stiffer spine knowing that I'd have extra arrow in the front and would allow me to add point weight to tune them out.  I usually shoot 29" arrows but I kept the 250s full length (32 3/4") since there's no real disadvantage to having that extra length.  So, all this allows me to shoot an arrow that's above 10 grains/pound.

So...having said all that, choose a spine for 56# and keep in mind that having them longer than 29" is always an option.

PS:  For future reference, this topic is better suited for the Pow Wow.

I find that Easton arrow charts are on the stiff side for most traditional bows in my opinion.I pick an arrow spine and bareshaft tune it to my shooting and bow.And let my tuning determine the arrows final length.

I would guess that 2018's could be the right arrow shaft.

If you are overdrawing 2" for a total of 30" of draw, then 29 5/8" is too short. You should leave 3/4 to an inch of clearance for keeping broadheads offa the shelf when you may be in an excited state. That would mean about a 31" arrow for you.

Just thought I would throw that wrench in there.

2117 will work at 31" with 125 gr point.
No way would you want a 2219.

I would use the cx heritage series 250's

Thank you Killdeer. I couldn't figure out how that worked. My draw is 30. I cut my arrows to 30.5 add the nock for .5"

I would say you may be a tad over 56#s as those bows stack a bit past 29"s or so, but with a 31" arrow I would say a 2020 would be darn close with 125 up front. If you go with carbon and a CE Heriatge 250 than you will want 200-225 point weight for good flight. Shawn

My one bow matches up with yours pretty closely.  It's 50# @28 and I draw 29.5" with arrows cut to 30".  The bow likes 2117 or 2215 with either 125 or 145 grain points or broadheads.  Both these sizes barehaft almost perfectly for me.  I won't think you'd need 2216 and definitely not 2219.
