They all look great! I urge you all to make sure you try the RN4081 with the copper. You may not need to use the 510 on it! I am a 510 fan myself but the RN4081 does offer something quite different. TH and flavor is totally unique in my opinion. The only problem I have with this atty is that I am not a cart fan. I have an 801 adapter from Rick and the 6v works well with it!
An RN4081 to 510 adapter would be great Rick!

Can't wait to get my hands on my upgrade!
