I have a Tremec 3550 with faceplated 2nd gear and proshifted 3rd and 4th that I just put in. After about the second shift I had learned it "sweet" spot to be able to upshift on the street. I can either double clutch it or wait for the rpms to come down below 1,800 rpms and it will slide right in with no noise at all and you can just ease it in. Downshifting took a little more time getting used to. I would say it took about 30 minutes of driving to figure it out. Downshifting to 3rd is just slamming it in gear and I get a small clunk that way and downshifting to 2nd, I have to blip the throttle slightly and slam it in gear and get a little louder clunk but thats it, no grinding at all. It literally took me about 30 minutes to learn how to do everything with this trans and its great, especially under power. I don't daily drive my car, but I also wouldn't hesitate to drive it at anytime. I would have driven it to work yesterday and today if I hadn't have bent 2 pushrods when I was trying out the new trans.
