Well, in fact they are not quite a decent group to talk about, even objective.
For some time, their trips (as guests foreign or in Bulgaria) were sponsored by the management, they only had to pay a very small amount (i.e. they pay 2.5 euro to travel 200 km and back, some of this sort).
But recently some of them decided to separate from the main bunch of the fans and went to the curva.http://img227.imageshack.us/img227/6636/fp...m0eae3b9pu9.jpg
I think they only have one group - "Street Fighters Lovech Town", the other flags, I guess, are just... flags?
My personal opinion is that they are crazy villagers. :D They show lack of originality (songs, striscioni, etc.), they aren't what one can call "ultras" or "hooligans". Though they had some clashes with Dinamo Bucharest in 2005, haha. :D
Here, in Bulgaria, mainly 4 clubs have the amount and quality of fans, which actions you might wish to watch - Levski Sofia and cska Sofia and the 2 Plovdiv teams - Botev and Loko. The other teams' supporters also try to do some cool stuff but often it isn't good enough.
But, after all, it's all your decision, the upper text is only my point of view. ;)
