rucksack and a 17 amp same as mark, swaped from a shoulder bag last year, a lot better for me personaly
I have the 18 amp belt pack with the Light force,went out with Dawn Raider on his permission ,Wednesday,first field ,no light ,the solder had come off a connection,the leads on the Lightforce are shit, lamps good .I find by the end of the night the belt is around my knees and I'm nearly on mine! All right for a big lump like you Tommo!
i use the ame as you mate i think the belt packs are a great job just make sure it on tight or your never done trying to fix it
