Well you asked so I will say it: I think you're making a dumb move.
I have a xxx in my bag. When I throw. FH approach shot it's one of the last options I consider. Inside typical approach range (250-100') for a fh shot I would reach for my putter if its on the shorter side and for a longer shot either an Axis or Vector.
The XXX requires so much more force to fly the same distance, and fades really, really hard. I would rather flick my Axis on a hyzer and let it glide out then touch down and stop with control.
I think you'd be a lot better off buying a slightly overstable mid in the class of roc / vector / wasp and learning to throw standstill hyzer flicks. If you can't make a disc like that fade on a 200' shot, much less a neutral mid or putter, ya gots something going on in your throw.
Check out this vid of me flicking the axis and lat 64 fuse...neither being known as a "sidearm mid" http://www.youtube.com/watch?v=z3FEFoWRIMc&t=1m10s
