Thanks Guys, I've had a number of pocket size 10X25's and have found that the power is good , but quality is not the greatest and after using some 10X40's this passed spring that had the quaulity they were just a little large for my liking to carry on chest straps. So I have poundered with the idea of getting a pair inbewteen. So I have bought a pair of 10X30 Zeiss the size and weight is about right and I'm hoping these will hit the two worlds I was after. Got them on Ebay aswell...BT
