Kinda depends on your application and your priorities.
If you are not tuned down to a gnat’s eye, probably any 600 with 3X4” fletch will shoot field points to the same POI as what you’ve got with the Centershots. Warriors are inexpensive and shoot fine. Tributes/Jazz can be had in 1816 or 1916 aluminum and they are REALLY inexpensive if you don’t often hit really hard objects or 3D critters.
If cost is less of a concern and you want minimal impact on your tune, there are lots of carbons in that general diameter of the Centershots. I think the Legacy Carbons may be the direct successors to the CS.
I just happen to be the kind of guy who breaks more than he loses, so I prefer the slightly beefier-diameter wood-grain carbons which fit well inside a 2117 footing. I cut the carbons to 3/4” short of finished length and then glue on 1 1/2” of 2117 with a 2117 Aluminum RPS insert in there. Then when I screw up, it usually tears off the insert, whereupon I file through the wall of what footing remains and replace the footing, insert and point. Yeah, I buy points by the hundred, I was gifted an ample supply of 2117 inserts, and bent 2117s are pretty easy to come by, even if you don’t have a bow that shoots them. The black, “400” GGIIs are also 2117s…. I don’t mind snapping off the Al footings when I hit a rock, but it really chaps me when a gorilla-glued footing slides off inside of a well-hit target, so I don’t bother footing the skinnier shafts anymore.
Really, my advice on carbon diameter is thsi: Standardize. If you want aluminum footings, buy GT Trads or Black Eagles in 600. If you don’t figure you need that footings, just pick a shaft diameter that suits you and stick with it so that you can re- use nocks, points and & inserts as needed. You will accumulate enough odds and ends as it is, without setting yourself up with components for 18XX-22XX or larger…
