In order to keep your 70 twink in the 70 bracket, you have to turn off your XP gain... this will pretty much place you in the twink bracket where you face off against players with similar twink gear. Every so often I'll see some mega twinks wander into a normal BG during holiday weekends at which point I rage, "I HOPE YOU LEVEL YOU DIRTY TWINK! YOU DON'T BELONG HERE!"
Anyway, you can keep your 70 twink in the non-twink bracket as long as you don't upgrade to WotLK. Depending on how much you enjoy annihilating non-twinked BGs, you can buy a WoW battlechest, upgrade to TBC expansion pack and queue up into normal BGs. This way you'll cap out XP at level 70 without having to fight other twinks by turning off XP.
