Eagle Optics just sent me a pair of brand new 8.5X42 Swarovisions after waiting a lifetime to purchase a set of alpha quality binoculars. I have no problem holding my 8X32 Vipers steady, but I just cannot get along with the larger Swarovskis. It looks like I am going to trade in the Swarovskis for either a set of 12X36 or 10X42 Canon IS binoculars. I am leaning heavily towards the 10X42 but am wondering if I would actually see more detail with the 12X36 and save some weight in the process. It is not possible for me to try them out at a store before I buy them.
