Currently I'm making tracks by using using Reason as a slave wired through Ableton. I'm finding it handy as I can have each instrument if I want played on a different channel in Ableton which then lets me throw any VST's onto any instrument I want, as well as just finding the automation control of Live just so much better than Reasons which makes it easier to tweak sounds so they sound right.
I've also found that using Rewire to connect the two has taught me a shit lot more about the Reason sequencer as well. The main Reason I started using both was I had a terrible time with the sequencer in Reason so I was just cutting loops in Reason then sequencing them in Ableton, now I'm fairly happyish mashing up stuff in Reason.
i hear this is the way to go..
