I'm big on he delrin dts too. Shorter version of the CV tips would be great.Agreed, I wouldn't want to go thin enough to reduce the flow. I think I'D rather just do the caps and tips separate.
That being said I much prefer delrin tips to any metal tips.
I have a SS Origen dt that also works very well but it can heat up quite a bit. Something like it in delrin would be about as perfect as I can imagine. The bore on it looks just a bit shy of the Cloud Chaser tips.
