I would suggest go with L30. If thavar 888p runs shorter, that;s because of the prestacking,. This will disappear after the first washing. Again, not to confuse you, but my both L32 888Ps differ a whole inch in length. You van see some posts above in this thread, I have posted pictures of my both 32/32 and you can see the difference. One of them came with no prestacking at all. Go with your usual thavar size.
