The Kiwis clearly got the version of Galle leaning more toward normal cricket pitch than dustbowl.So Tim Southee bowled 50 overs for 2 wickets on those decks, off that alone you just can't pick boland. SL made a lazy 600 and even NZ made 300 on a day 3 deck so you can make runs
The First Test was pretty close. The second Test the Sri Lankans made a million in the first dig then rag-dolled the Kiwis for nothing in their first attempt. It clearly wasn't that bad ( All out for 88 ) cos the Kiwis did OK second time around as you said. I might see if I can dig them up on Youtube and have a look. I didn't see either live at the time.
I don't know if it was the same pitch "refreshed" ( Like Pak did to the Poms ) or a different one.
