Asked to pick between Sehwag, who plundered the Kiwi attack at will while aggregating 299 runs from the five ODIs, and the imperious Tendulkar (244 in three matches), O'Brien chose the Delhi opener for his destructive abilities.

"Sehwag's pretty amazing, isn't he? He has been destructive. Though Tendulkar was amazing in Christchurch, I would pick Sehwag," he said.

O'Brien, who managed just three wickets in the ODI series, said he was hoping for an easier time in the Test series that starts March 18.

"In Test cricket you can bowl to individual plans for a longer period. When you have got more traditional batters, it makes life little bit less exciting. But it makes my job a little bit easier," said O'Brien.

"I love playing Test cricket, though I enjoy one-day cricket too. Test cricket is where I want to make myself a name and I am looking forward to it."

Despite his lackluster show in the ODIs, O'Brien said his career has not slipped back.

"It has just taken a little curve off the road. I am not concerned about it. Just like with everything, you do go up and down. You have good days and bad days, and I have had a couple of bad days. It doesn't change me as a bowler, and it doesn't change me as a person," said O'Brien.

But he said it felt good to come away with a couple of wickets in the last game at Auckland, which New Zealand won by eight wickets.

"It was nice to get a couple of wickets in the end. These tail-end wickets make you look good for a wee while, but deep down I wouldn't be particularly happy. But it is nice to take a couple to close out the series."

O'Brien said the series against India has brought back the crowds to the stadiums.

"It has been exciting to play this series against India. The feeling in the ground has been electrifying. The crowd has been amazing, nearly 17,000 and 21,000 Indian fans. It has been just noise. I am looking forward to it in the Test series as well," he said.

The 32-year-old paceman said the Test wickets won't be as flat as one-dayers.
