What lamp do you intend to use?
Are you on your own?
I lamp mainly on my own with a LF 170 8.5 amp pack and on foot. I am quite successful with this (85 foxes) so far this year.
The new gen lamps are very nice, how ever having it clipped to the rifle would not suit my walking style as I would have to sweep the field with the gun. With a clip on lamp I find I can hold the light above the fox until it is nearly in range then clip it on to shoot.
It just depends on what you are going to do...
