I'm sure this would be different for everyone. For me it took maybe two weeks. (must be slow). It was worth it cause last night I knocked off 13 streamers in just over an hour. (maybe that's slow?) . This has been no big deal. Once it's spooled up it lasts a long time. The bobbin works great, I wouldn't tie without it unless I had no choice. You don't lose anything you used to do, you just learn newer ways to do things. The vise ships with a good DVD to show you how to use the vise. All your tools still work fine. Use the standard bobbins for spooling floss or super fine klickhammer thread. I have the vise, the light (thats a great option), the fine point jaw and the tube jaw. Using the fine point I tighten the tension and use it like a standard rotary. The tube vise is great! I did make two extensions for tying tubes with the jointed plastic on. Once that was done I found there wasn't much else I needed for tying anything. I must admit I don't tie flies on hooks bigger than 4/0 so I have no need for the large jaw. Hope all that helps.
