Which cage

Steel. Its heavy but it breaths better and is better for long term use.
If I was in the market for a new one I would go micro.
I must disagree with my esteemed colleague. 🧐

The Silicone ones you talked about are usually resin. Go on Amazon and you'll see there a huge verity, a lot probably being 3D printed. Cheaper only $30 and a lot come with multiple size rings for the correct fit and a choice of tube sizes.

I do agree with the weight on the metal ones is a sensation the resin ones lack but you have a verity of colors and styles you don't get with the steel.
