Which fork for building internal ATSC tuners?

I'm getting ready to setup a new build environment for testing my internal ATSC tuners. Now that I've sorted out my other hardware settings under both kszaq's 7.0.2.xxx builds/fork and afl1's 7.0.2.004.x builds/fork...my question is which should I use for my base for testing?

From what I can tell, afl1 has DVB tuners working in his builds but kszaq has not been able to get them working in his builds. If I remember correctly from previous posts, something changed in the kernel???

If this is the case - I assume I would have to use the older base that afl1 is building from? Or since I am patching together from various builds (firmware, drivers, etc) should I exepriment from kszaq's fork??

Or should I start from something like wrxtsy's wetek play 2 fork? The following patch contains most of the ATSC elements I will need to work in:
li17-wetek_dvb.patch

Thanks for the advice on where to start. I don't mind the long road of experimenting, testing, changing, repeat...but it helps if you start down the right path!
