I see that you are a reseller/dealer of these items. If the waters ever part just right for me...I will get with you on exactly what I am wanting to do then you can tell me what I need and get me a price up for the materials if that sounds good to you?Regular incandescent ropelight seems to be the best if you want actual "Rope" (Round / low intensity). LED rope tend to be problematic as it can be more directional and has to be positioned carefully in some cases. Likewise the cutting distance on the 120v/LED versions can be troublesome to work with.
If you want LED I would recommend any of the LED tapes / flexible strips. I occasionally have blue tapes, but if you want a color you may also want to consider the RGB (color changing)variation. You can use single color RED / BLUE / GREEN with just simple switching, or buy a controller and get some fancy blends, fades, or just about any color.
