Switching from CFOP to Roux/ZZ

I recently learned Roux and ZZ and have more fun solving with them. Coming from someone who has made the switch themselves, how long did it take until you were as comfortable with the new method and were averaging around the same as you were with CFOP?

Currently I average around 25 seconds using cfop, 60 with Roux and just over a minute with ZZ. I want to switch but the slower times can be off putting and I find myself going back to CFOP.
