I made a board I can screw to my bench. It has two straight, full length, 90 deg grooves routed out. One deeper than the other. I use this board and a small plane. I can reduce a fat shoot in about 5 - 10 minutes with the plane.
Your plane blade should be as sharp as it is possible to get it. You should be able to shave hairs off the back of your hand easily.
Get the shoots as straight as possible before any reducing.
Once they are close to diameter I switch to 60 grit and a sanding block with a circular groove, just over shaft diameter like 7/16ths. This enables you to get the shaft perfectly round after planning with very little effort.
Spine and check weights.
Continue until they are matched close enough for you.
Over here hazel is our primo, easy to collect shoot shaft wood. A dozen finished arrows from pre-seasoned shafts is a full days work. They are worth it though, very strong.
