Hi all,
Im also very much in hula hooping and in love with my new hoop! I've been looking everywhere for one of those big chunky hoops and luckily i managed to get hold of one after a friend at Uni told me about a circus specialist company http://flamesngames.co.uk/ that make there own Hula Hoops!
For anyone that is looking to by a proper Hula Hoop check out
Flames 'N Games Hula Hoops they stock a massive range of hoops!!
Hope this helps!
