Re: Size 3 tip tops?
I've dealt with John an Englishman living in Florida however I'd check out Pacbay or one of The other retailers for tip sizes or buy The Blank first then chase The Tip.
The US system for Tip tops are usually in 1/64 inches ie a # 4 is usually 1/16 of an inch.
If a # 3 is 3 mm it would be around 1/8 of an inch which would be a big tip for a 7 Wt Fly Rod ??
