Messiah 2.0 + HD Loader + PAL PS2

I have a HD + pal v10 ps2.

I might get it chipped, and the dealer I know only does the messiah 2.0 and romeo mod.

Should I get the messiah, what are the problems if I use it with HDLoader, from the MC with a psx trigger disc. Would it still work? Or would I have to make a copy to cd and use that?

It still works. I have tried this, but with a different modchip/ps2 combination.
