Is the bow cut to center or beyond???
Four fletch may be more than ya need. I shoot Trad lites at 29.5" with my true 28" draw. My shafts weigh 331gn without feathers or paint. My BH setup is a total of 176 gns. and I use the AD alum insert.
I three fletch with 5-5.75" shield fletch. This arrow shoots like a laser out of my Widow PL X 51# @ 28". All together I get between 9.6 and 9.9 gns/lb of draw. I can also add the 100 gn brass insert and they still fly great and have woooo FOC.
These arrows have proven themselves on deer, hogs and turkey. I would add the 100 grn brass insert if I was going to be hunting moose or elk.
I have tried the Hammer Head Lites and found them to shoot well also.
You should find the AD's generally easier to tune to your bow than some other shafts MHO...
All that being said, I have considered trying 4 x 4" or even 4 x 3" just for grins.
Let me know if ya need more help.. PM or email
