I Recommend The Karrimor SF Sabre 45. Great piece of kit and PLCE side pouch compatible. The Berghaus Centurio 45 is excellent too, but keep in mind the Centurio is not PLCE compatible, you have to have the MMPS side pouches for those. Do not trust your gear to a Tescos rucksack!! it will end in badly!! I have seen plenty of people make that very mistake...it may seem robust enough at the beginning, but it doesn't take much stress for it to start to fall to pieces.
