Thinking about getting back into control line with a Topflite Tutor (circa 1982) kit.  I have a couple of Fox and OS Max 35s from that era.  I need a complete NVA for the OS Max 35s and either a tapered needle or a complete NVA for the Foxes.  I was never a fan of the original Fox NVA and am wondering if there are any better alternatives? 

I believe the OS Max and the Fox 35 spray bars are 0.155 OD.
