Troy Lee glove sizing

How do Troy Lee gloves size up? I have large Specialized gloves and medium Sombrio gloves. Alternatively, anyone know somewhere around Bristol that have them to try on?

And any idea what the difference is between the ‘Headline – White’ and the ‘White’ versions CRC have?

I’ve got 2 pairs of TLD XC gloves in Medium (size 9) and they’re bang on with standard glove site charts. I got myself a pair of Endura gloves in medium but they’re a wee bit smaller.
