Boxing - Colour or B&W

I've been asked to cover a charity boxing event again this year so decided to look through last years photos. I thought some might look good in B&W, what do you think?

I think in general the B&W works better, makes them more dramatic.

The exception is the one with the blood drops in the air - as B&W it's not clear what it is, the colour is important in that one.

1, 2 and 4 for me. Have you considered converting with a coloured filter applied or playing with the contrast and brightness, they look like straight conversions. Higher contrast might add to the drama.

I not a fan of coloured filters look really, I did have a bit of a play they aren't straight conversions but I must admit I'm new to B&W conversions and have a lot to learn.

Here's straight conversion top and bottom after adjustments

Colour is my vote particularly the one with the welsh flag

I think the adjusted version is better. There could even be room for more tweaking (IMO).
