I have to agree with DarrellH, tex. That 2315 is way overspine for 55 pounds and 28" draw with a 100 gn tip. You need to be looking at the 2215 instead. 2117 is also correct for you, but it's substantially heavier than your 2315. I'd be inclined to go to a 3-39 ACC, if you can afford it.

Or, for a more affordable arrow, try the GoldTip XT in 5575. It'd be fine for deer, though I'd probably go with the heft of the 2117 for anything tougher... like hogs, for instance.
