I normally make my own cork arbors. I wanted to tried the graphite and poly arbors. I did two steelhead blanks with them.
I glued them into the reel seats. Then drilled them out with my Rockler self centering drill press. The handles are done. The rods haven’t been fished with yet. So I don’t know if the arbors are more sensitive, more durable etc. So far they seem good. Easier than make cork arbors out of 1/2” rings
The arbors are a little shorter I cut one up and used two pieces. That are also smaller in diameter than your size 17 reel seat. Use a little more glue than normal to fill in
