Yes I know.

Very very very broad question. I just want to view a range of peoples opinions and why.
It is to accompany my K20/K24 DC5R sometime next year.

I am not doing this for popularity votes, but rather to allow myself to see both sides of the picture and to view both pros and cons for each.

I am aware of the issues and the amount of supporting modifications I am up for. But I just cant resist. It's the bug!! Once you get it, you're in it for good. You seek more and more power!

No conflict please. All opinions are welcome.
