you can skimp on rods, waders, and just about all the other gear. You can NOT skip on optics if you are going to sight fish! Of course if you can't see the fish anyway, buy the cheapies.
By the way go amber unless you have high contrast. Personally, I have just gone amber in all my frames. But I probably have several thousand in optics by now. Thank god for sponsors. Oh yeah Action Optics Padre's have lasted 3 seasons now. I've only had Costa Del Mars one season and they broke the first week when I sat on them. I have yet to have an Orvis frame make it even one season. They get a big thumbs down. With most of the poor quality frames the UV will eat the plastic and the lenses will pop out in no time.
