SF4 on PS3 - any server difference with different disc?

[onering]

I just got a PS3 and am gonna pick up SF4. I know that the PS3 is region-free for games, and wondered if there is any difference in which disc version I get.

I can pickup an asia/hong kong disc fairly cheap, but I heard that this one connects to asian servers for online play.

I'd rather play on UK/european servers due to lag, so should I get a UK/PAL version of SF4 instead?

Or does the disc version not matter anyway? Is there any way to specify which server you will be joining for online play?

Thanks.

I can get hold of SF4 asia/japan version for around £25 new. Not much saving I guess but I can't seem to find it much cheaper online in the UK though...
