needle groupings…

Hey all, not sure if this is the right topic, but saw some other stuff about needles in here , so… here i go…

let me start by saying that i have utilized fake skins and that large chunk of formerly “naked” patch of skin above my right knee for practice…

have a lining question though, ordered some 11RL’s (loose configuration) (working on a traditional piece) and i like the thicker line style, forgot where i had ordered them from and am now curious if an 11RS would fit the bill for what im looking for? Does it make that big of a deal if i am lining with an RS or a RL (other than the stated names of what i am using) as long as i have my “liner” machine set as i would utilizing a RL…?

I hope that you guys and gals can decipher what i am actually trying to convey here… any responses would be appreciated!

Thank you!
