Paul Nelson is backing himself to have got The Shackler's Wellington Hurdle (3400m) preparation pin-point perfect as he bids for a feature jumps "double-double" on Saturday.

The Shackler coped admirably at Trentham with both weight of expectation and the top of handicap.

Paul Nelson can’t fault The Shackler ahead of Trentham, but he is concerned with the jumper’s weight.

The Shackler claimed the first prestige event of the jumping season when second best at Te Rapa had looked more likely to be his reward.

Dashing jumper The Shackler was his own worst enemy at Hastings, but he was nimble enough to get himself out of trouble to post a memorable home track victory.
