    I'm shooting the 75/95's out of my 70# insanity and so far so good. I was told I'm slightly over spined bit I both the wrong shafts on accident so I'm making due. Shoots well with them but if I back down the #'s at all I'm going to need new arrows I think.

    If they are for hunting..... When in doubt, go stiffer.

    My opinions are MY OPINIONS. Take them for what they are worth.

    Hard speed bow like Insanity the 75/95XT would be best choice.

    Great arrow, used them for years now.

    Velocity 300's or the equivalent. 30" draw, nearly 30" arrow will need all the spine it can get. The 75/95 can be MADE to shoot but at what cost spec wise?

    With those specs a 35/55 (.400) spine arrow is way too weak and a 75/95 (.340) spine arrow is also weak. I think you are going to find an arrow with a .300 spine is going to fly much better for you, especially after putting on broadheads and shooting anything beyond 30 yards.

    OT2 specs out a .2775 as optimal spine with your setup. The Insanity is an aggressive bow and the Insanity/Invasion are known for shooting and grouping better with stiff spines.

    Thought the same thing about my Primal and the bow is less agressive and my arrow was 2" shorter using feathers. Yes the 340 can be used but the OP will have an easier time with the 300.

    Arrow borderline on the backside of GT charts. Im sure the 300 will tune fine, possiable better,
    I myself perfer a stiffer spine.

    75/95 for sure, that said I'm gonna say .300 spine would be better yet. My Insanity tuned great with 350's at 28.7"/62# with 27.5" mat'l length.

    Goldtips has a 300 spine arrow in these Velocity XT arrows. If your shooting a heavy broadhead the 300 may very well be the better choice.

    I shoot 27 inch shafts in the .400 spine out of all my bows with a 100 grain tips, I choose light shafts such as carbontech cheetas and gold tip ultralights also. I shoot them from 345 fps all the way down to 285 fps with all different poundages and they shoot really well for me. Even my target bow has .400 spine with my harvestime redemptions and they are the fattest possible arrows with a 100 grain glue in tip and they shoot really well at 27 inch shaft.

    Key is to find your arrow shaft length that you want and then pick a spine that will shoot well at the speed you want, all of these things must be considered before choosing a random spine. For example my xjammer fat arrow has a .297 spine and at 28 inch shaft shoots exactly the same as my redemptions and I have shot a 60 x using one xjammer and 4 redemptions.

    I shoot 70# and a 28" arrow and I'm between a 300 and a 340 so I'd say a 300 for u for sure

    Anybody with common sense will know that an untuned bow (or wrong spine etc..) can still put an arrow close to its intended target at close range, as you step back in distance the accuracy is going to decrease and at longer distances the misses are going to be even greater.

    I shoot a 70# insanity with a 30in draw. 7595 shoot very good at long range but up close (20-30yrds) They whip back and forth a little as they try and straighten out. I just got Goldtip velocity 300 last week from South shore archery and problem fixed Perfect arrow flight at all distances If you go by the chart at carbon express the insanity set at my specs needs an arrow with a spine for a #83 bow. All I can say is I tried it and it works. My Slick trick Magnums are flying as good as my field points as far back as I can shoot and still hit the vitals most of the time on my 3d target .....110 yrds The 300's are a tad lighter as well @ 8.5 per inch. I didn't think it would be much different in trajectory then the 7595s but I had to adjust my sight quit a bit higher than the 7595s. In my mind the stiffer shafts are using the bows thrust better.

    That depends on the components and the weight of them buddy...you can't make an comment like yours without more information.

    And, for the record, I shoot a 70#, 26.5" Z7 Magnum and I have to use .340s. Then again, I have 175 grains up front to counter the spine.

    Read more...post less.

    If you are using a arrow companys chart to determine spine you have a LOT to learn buddy...those charts are as antiquated as the information you are spouting from me.

    I shoot an invasion and the bow shot better at long distance using a .300 spine OP. I was shooting 75/95 which are .340 spine and went the stiffer spine. My groups are better at 40-60 yards. Try the Velocities in .300 you will like your broadhead flight better.
