I like all sizes. 8X is the very best for everything. I have a pair of Swaro NL8X that I like a lot. I have several pairs of 10X EL and SLCHD and like the NLs a bit better. I also have 12 and 18 X Vortex UHDs and they draw no flies. They are excellent. Just for bopping around I have two pairs of 8X30 Binos. Conquest 8X30 HD and Swaro 8X30 CL. I have Swaro 10X25 CL Pockets as well.
