I just buy the cheapest carbon arrows on the shelf at bass pro. I have had great luck for Me and my Kids. Plastic fletching. I just buy the arrow that matches my draw length and pull. The diagram on the back of the box helps, or just ask someone behind the counter. They will trim and glue them for You. Or I go to Impact Archery, on Dean Marten. Local Mom and Pop type shop.
Back in the days when I was shooting and bowhunting a lot, I used the Easton metal shafts but we didn't use (or have available?) solid plastic fletchings. They were imitation feathers and that seemed like a good structure. Seems like if the solid plastic ones bent due to heat or impact they'd make the arrows err in flight under some conditions.
But one thing I noted was that when lofting arrows at game in the field with hunting broadheads, they seemed to float more than the field tips I practiced with. The broadheads seemed to act as wings on the front of the arrow. I began practicing with blunt practice broadheads for just that reason, though they can be tough to remove from targets.
Model: Defender Elite (9.3 GPI)
Length: 29" (carbon to carbon)
Fletching: Blazer Vane
Insert: 75 grain brass
Broadhead: Swhacker (for practice, I use a plain-jane 100 grain field tip)
Total arrow weight: 480 grains
I love a heavy arrow with a decently high FOC. It shoots accurately for me and bucks the wind very well. I'm thinking of switching to a micro-diameter arrow (4mm), but perhaps I should just leave well enough alone and not try to fix things that ain't broke.
