Easton Flatliner Arrows
 

Has anybody tried these arrows yet? They are extremely light with the 340's at 8.2 grains per inch. Would they be comparable to the Carbon Express Maxima?

i know they took the place of the light speeds and they have a new nock design and something else maybe its a new insert design i cant remember but they are about 6fps faster than the lightspeeds of the same weight so i am told. i know most of the guys at my local pro shop are shooting them this year. one of them was shooting the maximas and he said the flatlines shot more true than the maximas and they shot better through paper... well at least they did through his bow.

what's the difference between needing certain weight (grains) to prevent dry firing your bow and needing the proper spine stifness for accuracy and true arrow flight? i guess what i'm asking is...i shoot Beman Realtree MFX 340's at 10.4 grains per inch. i was told this is about as light as you can go for my bow (76# /w 30" arrows) without dry firing it. so how could i use the same "340" arrows that are that much lighter (2.2 grains per inch) without damaging my bow? correct me if i'm wrong but isn't "340" something to do with the spine and not grains per inch. if this is true than you aren't really gaining anything if you still have to shoot arrows at certain weights. your just shooting stiffer arrows, not "lighter" arrows.

the 340 has to do with the spine stiffness which is the deflection in inches represented .340" and im pretty sure thats not true about that being the lightest arrow you can shoot. i have shot the 500 lightspeeds out of my bow which are 6.5gpi on 70# and a 29" draw. so for example there should be no problem with your bow if you wanted to shoot the 340 flatlines wich are 8.2gpi to pick up a little speed. Some arrow websites have an arrow chart that says what arrow to use on this many pounds with this number draw length so you can get an idea of what arrow to use but i bet thats what they are basing it off of.

where is a chart that will tell you the minimal amount of grains you can shoot out of a 76 pound bow.

The 340 is the spine, you get that off of a chart that the manufacturers put out. The minimum amount of weight you should shoot is 5 grains per pound of draw weight, this is how they determine IBO speed. Most people agree that you should shoot an arrow that weighs 6 grains per pound. The absolute minimum weight arrow out of a 76# bow is 5 x 76= 380 grains. At this weight the bow would become pretty noisy so I believe also that 6 grains is a better starting point, 6 x 76 = 456 grain arrow. The ones that your using now weigh 10.4 x 30 = 312 grains. Then add 100 grains for the tip and about another 35 grains for inserts, nocks and fletchings for a total of about 447 grains. I'd stay right where you are and not go any lighter.

There is a chart on the cx website.
I know about the minimum 5 grains per pound of draw weight and i should be shooting a 350 grain arrow but my lightspeeds are 320 grains but my drenalin shoots them well for target shooting and it is dead queit.
On the chart for 76-81#s it list the maxima 350 hunter and coming from your bow it would weigh about 402 grains which would be under the 380 grain minimum

thanx Centaur!

I was shooting Beman 340 Hunters for afew yrs now....Went and bought a Dozen Flatliner 340's today had em cut to 29" with 100grn tips....Chrono was a stedy 268 with all 12,my Bemans were 254-256fps.I did get a few 269's but that was me I think,my Drenlin is set at 65lbs and 29" draw......Smashed one arrow right away gerrrrrr......down to 11 now hahahaha...

THe reason I am thinking about going to them is that they are listed as the same weight as the Carbon Express maxima's. 8.2 grains. But they are a lot less expsensive as the maximas.
