User opions wanted, Wavpack vs Ogg vs MPC (crippled) Options

[Progenator]

Hi,
I recently installed Rockbox firmware on my Iriver I-hp 120, and quite stoked about it, its great.
I am befuddled though, as to which lossy format to use. I know MPC is supposed to be the best at 128kbps and up, but the MPC plays but does not seek with it. I have seen posts here (at hydrgogen audio) with people saying MPC at insane may as well be considered lossless for listening purposes. Is it that good? If it is, I would go without the seeking for music.
Quality AND size are my considerations. I tend to encode my stuff at 160-220 weighing both factors. For my car steareo I used lame at 320. I can definately notice the difference between an ogg and lame at the same bitrates (Radiohead - Karma Police at 160) .

I also don't know how a lossy wavpack (which is well supported on the rockbox) compares to OGG or MPC. I'd assume in quality: 1. MPC 2. OGG 3.Wavpack, but thats just an assumption.

Would like some opinions on this and maybe an all inclusive lossy format test.

WavPack really doesn't make any sense as a stand-alone lossy codec, except maybe at very high bitrates (>320 kbps) or when you are forced to transcode to or from another lossy format.

However, the hybrid mode is handy for RockBox because you can keep the correction files on your PC for lossless and just copy the lossy versions to your portable.
