back - green radikal 90a boardside, JimZ 85a black top roadside. Front - all JimZ white82.5a. You can also just run with JimZ all-round black at the back white at the front. I just personally prefer a slightly harder main back bushing than the JimZ (side note: they don't make green radikals anymore).

back - Green93a/Red90a venom barrel. Front - red90a/yellow85a venom barrel. Given the way venoms perform you could also just run with green all round.
Ado can tell you more about the reflex bushings I'm sure there is a combo in reflex that would work awesome.
The main thing to consider is you want lots of barrel or stepped thane at both ends and in both bushings. A bit harder at the back, a bit softer at the front and if possible you should do one duro softer on roadside if you get my drift.
