Spine question

I am new to all this, thus my question.

I shoot an 06 Trykon-29 DL @ 65# (probably will increase to 67-68 soon). I currently use a Redhead Carbon Maxx 6075 arrow at 350gr total weight.

I was looking to change arrows (the above seem fine and have had no problems). I bought the OnTarget software to help me out here, but some of the "matches" for my set up only list either too weak or too stiff a spine......with no "good" match. I figured too weak of a spine was bad, but couldn't figure out if too stiff was bad also.

I want to find one arrow that I can use for both target (informal) shooting and hunting (wild hogs and deer). I also wanted a lightweight, carbon arrow similar to the above.

Thanks.

I should also state that the current shaft length excluding the nock is 27" (set up this way by 2 different pro shops- isn't this a little short?) and 27 1/2" to valley of nock. I use Blazers and 100gr FT/BH tips. My total arrow weight is consistently 350gr w/in 2gr.

Thanks guys.....this is the input I was looking for....

I will make the changes to the database as recommended.
