ALL of these opinionated recommendations are guidelines of sorts, at best. ALL will be "ballpark" for anyone.
your bow and you will decide what works best, and how best the arrow will need to be built with regards to its length and point weight (non-broadhead and broadhead), and resulting FOC.
if at all possible, get 3 full length shafts of each bemans, 600 and 500, and do the testing.
fwiw (though it really shouldn't matter for anyone but me), i have a 29" draw and my shaft of choice is the beman 500, 29-1/4" (i pull 'til the point back end touches the riser - that's my "draw check" of sorts), used with mild r/d longbows and AFL hill style longbows with holding weights of 43# to 52#, variable total front end weights (adapters and points) of 145 to 350 gains, low profile 75-x105 banana offset 4-fletch, or high profile shield full helical 3-fletch.
good luck in yer shaft and arrow quest.
