Didn't know where to post this so...

I was always wanting thr 4/6 with the 20" wheels, however, I know when I swap to a LS1, LQ4 or LQ9 around the end of this year that I have heard that 2/4 and 18s would be a better option for performance...
I'm looking for performance and appearance...
Also my truck is a daily driver and I don't know if 4/6 might be alittle too much for the florida potholes and parking bumpers...

So what should I do?
4/6 with 18"s
4/6 with 20"s
2/4 with 18"s
2/4 with 20"s
