Invaribly, those responding advise a minimun of at least 400 grain arrows ... which I'm very much in agreement with
Sure you can shoot 350 grains and that's what the industry as a whole does when quoting bow speeds.. (Kind of like the old IBO ratings used with vert. bowmanufactures, which everone knows is basically BS )
However, I wonder if these new members with repeated questions concerning their new bows or specifically bow "Packages", ever take the time to consider when looking at all of the stuff in the package,
if a "350 grain arrow is good, "...."why Excalibur put those 150 grain fields points in there" 
For , as everyone knows,
by the implications gained after reading the speeds quoted by Excalibur 
that 350 grains "WILL DO".In the very next post, however, light arrows, those below the often suggested 400 grains are then attributed to many of the limb failures experienced in many of the higher stress models.
Come On Folk, and possibly even Excalibur....
If you want us to shoot a Minimum of 400 grains which is indicated in your packaging when combining of a 250 gn Diablo with the 150 gn field point ,
Maybe it's time to quote speeds for your " Loyal Following", of actual speeds we can expect with a minimum 400 gn weight arrow as implied by your actual packaging practices as well as the many knowledgable members here..
Maybe many questions, as well as failed limbs, would be eliminated by the "un-written double standards" as far as minimm grain weights are concerned.
