Sorry buddy, I haven't decided yet, when I made up my mind I'll let you know. Thanks for your offer, cheers

Thanks mate, I guess a good PRaT should be punchy, impactful bass, and another thing I concern about the RS1i is its tremble, I wish HF2 could have more tremble. Looking forward to read your comparison. Cheers.
Doing some listens now....
But what do you mean by 'tremble'?
Ok, so I compared the two a bit.
HF-2's bass definitely has more impact. In general it's sound has way more body then RS1i. HF-2 gives a dark tonality to the complete sound spectrum though and could be considered somewhat laid-back for a Grado. (it's still not Sennheiser HD6X0 laid back offcourse but relatively in comparison with other Grado's).
The highs, or 'treble' if you will, goes further with RSi though. It's more upfront, more trebly, engaging and at higher volume it reaches the point of harshness and painful much sooner then HF-2. I also think RS1i is a tiny bit more detailed, or at least gives the impression of being more detailed.
It also has more of what I call 'dynamics'.
To be short: HF-2 has the 'body and slam', RS1i has the treble and mids texture.
For distortion gitars, RS1i is a bit more engaging and adventurous, but HF-2 is more complete because it has more body (but that comes from a D7000 lover, so I guess I can appreciate some bass and body).
Overal, I'd grab for RS1i with acoustical gitars and some lighter classic rock maybe. I'd grab for HF-2 with power rock, metal, progressive.
For other genres, I simply grab for other headphones, since they will do much better for my taste.
I have a pair of HF2s, and apparently similar taste in music. I’m looking for a bit more “crunch” in my guitars, and more impact in the bass. For instance, when a double-kick drum starts galloping, it’s well described and has a good amount of bass, but I want my ears to be pummeled by the sonic assault. Please post if you come across anything with a similar signature, but a bit more oomph. I guess we can always hope for a less-restrained HF-3…
HF2 is a good can for metal, not a exllent can for metal.
