In my experience, the charts are deeply rubbish at our drawlength/poundage. I say this every time, but what you should be looking at is the easton spine/weight comparison chart. Its on their
website. Find your perfect ali on it, then go left in a horizontal line. The carbon nearest that (ie with the same deflection) will be the right one for you.
That said, seeing as you seem not to know your perfect ali with your current setup that chart is pretty much useless too. Happily though, your arrows are exactly the same length, and draw weight exactly the same, as my set up. Which means that your perfect ali arrow is
probably 1516 XX75 (1514 or 1612 X7), and your perfect ACC therefore the 3L-00 or the 3-00. I have the 3-00 because I need my arrows on the stiffer side. See if you can try a 1516 ali of the right length - if they are right then either of the ACCs I mentioned should be fine. Remember though, if you go to try arrows at a shop they will refuse to cut them down for you to try, and so when you buy them and they are cut down, they will react stiffer. In other words if the ones you try seem only slightly too whippy, they'll be the right ones when they are cut down.
Regarding your sightmarks, having carbon arrows will make a difference, as even in the smaller sizes they are lighter than the equivalent spine alis. With ACCs you should reach 60yds and beyond with ease. I manage 70m fine with the same poundage/draw length. Feel free to PM me if you want more info. And if you're really desperate, I could arrange for you to try my ACCs. I'm going to sell them soonish anyway.
