Supposedly, this racquet was desiged for one piece stringing only, however if you do a search through the forums, you will find several threads about this that demonstrate everyone's different methods for hybrid stringing.
I have strung plenty of times now with hybrid stringing and had no problems.
You will notice there are no extra tie-off holes for hybrid stringing apps. So you will have to enlarge a grommet first. For two-piece stringing with the Donnay Pro One MP, i first used an awl and some chapstick to widen the grommet at the
9th hole at the top of the head. This should be a main string. You will use this hole to tie off and start your crosses. I have also used the 10th, but it the knot didn't seem to fit as well.
Your x-1/multifeel hyrbid sounds like a champ. I haven't used those two strings myself, but have read plenty of reviews. I have really enjoyed both Natural Gut and Kgut with this racquet. Even gosen Micro plays great. I am using cyberflash right now mixed in with various softer strings to add a little more spin and durability. I like this stick at any tension. I keep a couple strung loose (mid-high 40's) in case i am in the mood to play with more topspin.
* I also created a tie-off on the 11th hole from the head, which is a cross. This gives a lot more room for the knot. But I chose not to use it again because: (1) puts the knot closer to the ball striking area and i was afraid of premature breakage. (2) too much thinking and planning with floating clamps when in a hurry
