i changed my ariel to a smaller one as i think they look better but it didnt work in the ariel base so i put the old one back on and managed to snap it leaving some thread in the base i can pick a new base up cheap enough but cant get the old one off the roof any ideas or is it just a case of yanking it off, i phoned a local sound system place thinking they would be able to wip it off for a few quid just to get it done they said £75 what a rip off surley its not that difficult lol. thanks
