I need some help from all of you experts:

I just purchased a new Hoyt V tech and was trying to decide on the right aluminum arrow size (Easton Super Slams). The bow is a 28" draw set at 57#. I shoot a Fletcher Fletchunter release with a string loop and a Trophy Taker drop-away rest. I will be shooting a 125 grain, 4 blade Magnus broadhead. The Easton Chart recommends the following sizes as options: 2312, 2117, 2215, 2020, 2314, 2216. This set-up will only be used for hunting.

What do you guys recommend? Pros and cons of these sizes?
