Which Commercial Pool Brush Head Gives the Best Durability?

[nashroberto615]

Hi everyone,
I'm in the market for a commercial pool brush head and I want to make sure I get one that can withstand heavy, regular use without wearing out too quickly. There seem to be nylon, stainless steel, and mixed bristle options, but it's hard to tell which one truly lasts the longest.

For those with experience in pool maintenance, which commercial pool brush head do you find most durable? Are there certain materials or designs that hold up better over time?

Looking forward to your suggestions!
