Reply to windows 32 or 64bit best?? (S2 & Traktor)

Just got my S2 yesterday and having the same pop/crack issues as lots of others have (had same issues with VMS4 on both traktor and virtual DJ).

I sort of cured it on the VMS4 by setting up a partition with 32bit win7 on it (instead of 64bit) and a few windows tweaks. I want to do a clean install for my S2 (get rid of vms4 and asio drivers etc) but wondered if it's worth using 64bit for it or will that cause more problems?

Cheers!

Adam.
