Scott Nicholls twice beat two-time world champion Jason Crump as Eastbourne notched their second Elite League away win of the season, beating Belle Vue 48-42.
Nicholls got the Eagles off to a terrific start by heading home Crump in heat one with Lewis Bridger a handy third after he held up Belle Vue's Aussie No. 1 for three laps.
Then Nicholls rounded off the meeting by again getting the better of Crump in heat 15.

Crump, who broke the Arlington track record last month, passed Nicholls in that final race with a daredevil dive going into the first bend on the second lap.
Nicholls, though, superbly re-passed him next time around.
It was not as if the outcome of the meeting hinged on that final race.
Eagles had clinched victory with a 4-2 from Cameron Woodward and impressive reserve Simon Gustafsson in heat 14.
Solid scoring down the line was the key to their first win in Manchester for four years.
Nicholls was beaten by Crump in heat 13 and also by the faster-starting Charlie Gjedde in heat five.
But, with only the Lee Richardson failing to win a race for the Eagles as he struggled with a troublesome wrist, they had enough strength in depth to counter a mid-meeting revival by the injury-hit Aces, who lost Lukasz Jankowski after just one ride when he aggravated a shoulder injury.
Belle Vue wiped out a six-point deficit to level at 30-30 but successive 4-2s by the Eagles edged them towards the finishing line.
Gustafsson ended Gjedde's maximum hopes with a tapes-to-flag win in heat 12 and fellow reserve Brent Werner's contribution was also crucial.
Werner won the reserves' race and teamed up with Edward Kennett for a 5-1 in heat four when both Eagles passed home skipper Joe Screen, one on either side, coming off the second bend.
Eagles had a touch of bad luck when Woodward stopped on the third lap while challenging Screen for the lead in heat seven.
