I've got some frontier PC 8x25's which I love and am pretty sold on the brand. I want some bigger bins for planned trips (rather than take anywhere pocket ones) and am thinking either the 8x36 or 8x43's. There's not much in it weight wise and cost is a lot for me whichever I get, so my question is: will I notice a real benefit from the larger glass? And am I missing an obvious alternative for around £300?
