Do you have another preferred stylus? I have to admit that I was comfortable with the stylus for my Lite and though the pen that comes with the XL was laughable at first. I played through almost all of Hotel Dusk and Last Window exclusively with the pen stylus and now even the larger normal XL stylus seems small. I have a feeling the old Lite stylus would give me a good deal of grief now.
I use my thumb because a smudge here or there is preferable to the possibility of a scratch.
