Rip Curl Claw Gloves - Sizing Issue!

Been looking at gloves for a while and finally decided to go for the Rip Curl Core 5mm 3 Finger Claw Surf Glove - http://www.wetsuitoutlet.co.uk/product_info.php?products_id=1152
My current gloves are Sola (normal fingered glove) and a size XL, but I've just tried on my mates gloves (same as above) and bit of a squeeze but I managed to get them on and they're a size SMALL!!!
Should I therefore go for a size medium? As the small only felt tight on my thumb and forefinger, but everywhere else was perfect fit! Or should I go for my normal Large / XL size?
Anyone else who has these gloves I'd love to know what you think of them, and if you had similar size issues like me!
