i just noticed on ebay that you can get black nylon strings. thus i am one more step closer to having my geddy lee jazz be almost completely black in colour. questions: -are the nylons as smooth as d'addiros or smoother? i play classical guitar. are they as smooth as classical guitar strings? -what is the tension like? i want as low tension as possible. -what do they sound like? bright, thuddy etc? -is there anything i should know about them that might make me reconsider buying them? thanks!
