Ok, so after having some sleep apnea last night, I decided to rather wait for JB than going to 4.0.4. Then some genius posted about RR 3.0.5(ty merc...) and that got me thinking...
Since RR was mostly working I wanted it, but scared of issues I also decided to dual boot.
So as of 2:30am this morning I am on ICS 4.0.3 and RR3.0.5 on my secondary, and surprisingly I think the ROM is capable of a daily driver... Wifi, bt, 3g, in fact I haven't found anything that doesn't work. Its also smoother than my ICS 4.0.3 and voice recognition is MUCH MUCH MUCH better and can be used offline.
The dual boot setup was damn simple as well. I just flashed the latest Siyah kernel(don't do this if you running GB, only in ICS or JB), restarted into CWM app (pre-installed on the kernel), copied the RR3.0.5 zip onto mt phone and selected "flash to secondary" and voila, I have dual boot ICS and JB!!!!!!!
I suspect most of you know this but root/kernel flash/dual boot was new to me, I have only done a KIES update before... not bad for one night.

How did you flash Google Apps on the secondary rom?
