Best MTB helmet under £50?

Hi,

Got a branch to the forehead hard enough to put a dent in my helmet and give me what felt like whiplash two weeks ago.

Suggestions for best mtb helmet under £50?

I have a full face as well for uplift days. This one has to do regular 20 miles winch and plummet rides and very occasional all day in the peaks rides.

Ideally with a go pro mount for a light in winter or occasional go pro in summer.

Currently helmet is a Bell Super Air MIPS Helmet. It's fine but I can't quite get the straps off my ears so not a like for like replacement.

I have a 60cm head and wear hats under helmets in winter and a buff ( for sweat) in summer.

Thanks for any suggestions 😃
