i've done a bit fare of squeeking in the past, and had some good results, but if the foxes are'nt in that certain area, or have been lamped/squeeked before then your in for a quiet night .
pre ban i always preffered lamping from the motor simply because i could get on more gear, and catch foxes that were otherwise un-catchable, if a certain area is quiet then you simply move on to another one, and i would usually cover around 200 mile in the night and see plenty of everything.
it's like a lot of things though, you have to put the miles and hours in and have the right dogs to get the results
