Either way a few thoughts on the matter:
1. If you're flying easyjet a good trick for getting things on the plane that can't go into the cabin without paying for a bag is...tell them at the check in desk that you'd like to put you "carry on" bag in the hold. They always let you check it in for free.
2. When flying to South Africa via the middle east, some friends got every single bit of webbing in their carry-on bag cut. All their cams, QDs, harnesses etc. as they were a "strangulation risk"... Bizarre!
