I know there are lots of DR threads, but this is a little different. Can anyone who has tried Nickel Lo-Riders and Sunbeams compare the two? As far as I can tell the only difference is the shape of the core, but what kind of difference does that make with these two? I have been playing Hi-Beams for about a week now and I don't like them very much. They are too rough on my fingers. I'm used to slinkies, so I think the nickel is much better for me and I want to try one of the nickel DR's but can't afford to try them both.
