I am selling them because I have the 10x42 El's and I think the weight difference between them is not a whole lot. I used to have the 10x42 SLC, but I ended up getting rid of them to get the EL's. So as far as the trade, I am not interested in the 10x42 SLC's but I will gladly sell you my 8x30's. If you want some pictures, email me or reply and give me an email address. I take care of all my optics, and treat them better than any other piece of equipment I own. Any more questions feel free to ask.
