Help with new arrows to replace old school CX300's

[Mountaineer]

I am finally running low on my old Carbon Express CX300's. I have been shooting these style arrows since about 2007 - I had a bunch of them. Some of the arrows I'm shooting have killed multiple animals and still shoot great out of my Mathews Drenalin.

I'm not planning on getting a new bow in the next year or more so what brands/spine should I look at that may shoot similar or better. The CX 300s online search shows 8.0 gpi and .350 spine.

I shoot 100 gr fixed broadheads.

I like Gold Tip arrows.
Since I like to play with my FOC it's easy to add or remove weight behind the insert.
