Replacing Apple chip with Messiah 2 Pro

[XcodeX]

I have a V7 US ps2 modded with an Apple Chip, works great and i loved it. However, I've just got my hand on a new Messiah 2 pro chip.
The question I'd like to ask anyone who knows is: Is it worth the troubles to re-solder/replace the chips on my ps2? and are the solder point on the two chips different or are the pretty much the same?

Also, does the Messiah 2 pro allow me to play both Pal/Ntsc games without patching them? 'cause I've read the specs for the Messiah 2 that it has "True NTSC/PAL switching is incorporated".

If anyone can give me some tips on this, it would be greatly appreciated.

Thanx,
