Player-coach Andy Whalley said Guernsey's 9-2 demolition of Sonning in the EH Trophy second round was a fair reflection of a superb performance.
Guernsey have now been drawn to face City of Bath in the next round as they seek to defend the trophy.
"As a coach I'm delighted: everyone's working hard and it sets us up for the second half of the season," Whalley told BBC Guernsey.
"There were some goals which we almost walked it in after 20 or 30 passes."
Guernsey beat Banbury on penalty flicks in last season's final, having been beaten at the last hurdle in the two previous years.
And Whalley believes they have a squad good enough to make it four finals in a row.
"We've got some phenomenally talented individuals but actually it's building a team that we want to do here," he added.
"That's the difference between now and, say, five or six years ago - we've got a real squad now.
"We've got a new turf which is really fast so when we move it quickly and play two or three-touch hockey, the opposition just can't stay with us."
