I was thinking about switching to a easton skinny carbon arrow and was wondering if anyone has put 4 fletches on them.  Did not know if there was enough room to do that.  Also i shoot carbon express heritage 250 now what would be a easton spine to match that.  Shooting 53lbs at 28 inch draw 100 gr insert 200 grain head. Thanks very much fellas

There's plenty of room.  I run 3x5 with a lot of helical. 4 fletch would be fine.

Trap

On my scale, the CE 250s run about 5# heavier than the .400 Axis.

Take a look at the FMJ as well

With that much point weight you might want to go 340 spine...300 is a lot of point weight

I think a 29" 400 with 300 up front should be near perfect if your bow shelf is cut past center. My specs are nearly identical and 400's bare shaft perfect !

I used to put 3 fletch my Axis,but the last set I put 4-4" fletch on them.Fly great and no problem doing 4 fletch on an Axis.I come to like and prefer 4 fletch on all my arrows.I like the way they look and fly.

Soundin good to me i was wanting to drop a little bit in point weight so may be just perfect

Yep...I have 400 and 500 Axis shafts with 4X4 feathers on them. Shoot really nice.
