Agree with REDGUN! Taking out feathers and cutting them as prep for tying takes a good bit of time and same thing when you change tail colors. Now if am ready to tie with materials all ready, I do cut my flash strips ahead so I cut a whole package at one time. Also there are more than one way to tie in flash, there is a fast way and then their is my way which is each side is tied in individually and some go for speed and just tie in a longer piece of flash and double it over and wrap. So my slower way if I am using flash I will average a jig every 2 minutes or so, but no flash I will average one just a tiny bit over 1 minute. However this is only a big advantage when tying a number of the same color pattern. So the more of a jig I can tie without changing like when I do 100 for one guy that are all the same I can usually get that faster than I can say 10 jigs of different color and doing 10 each of them. That will take longer. So when guys talk about how long it takes to tie a jig there are a lot of ways to look at that too!
One other little factor is if one is trying to go as fast as they can or if there are really trying on each and every jig to make it as well made as they can. That will also make a difference in how long it takes to tie a jig. I believe if feathers are cut and no flash I am sure that I can tie a jig in a good bit less than one minute on one that all goes as I want it to. I say that because I am a perfectionist and if a tail is not wanting to look right after I have it tied in, I will take that sucker back off and re-do it again and again to get it right! So that even makes it more difficult to say how long it takes, LOL! I know there has been jigs that I had to tie the darn tail in 4 or more times! By the time I get one of them done, I am not happy at all!
