Guernsey FC boss Tony Vance says his new formation was "tested to the hilt" by struggling Redhill after the Green Lions were held to a 2-2 draw.
Vance has been experimenting with his side after their outside chance of the play-offs were ended, despite a 3-0 win over Sittingbourne on Saturday.
Guernsey led Redhill 2-1 after goals by Ross Allen and Marc McGrath before they conceded a late equaliser.
"The shape and formation was tested to the hilt," Vance told BBC Guernsey.
"We're trying out some new things at the moment, on Saturday we tried out a new shape and everything was nice and pretty, we were good on the ball and pretty dominant.
"After five or 10 minutes (against Redhill) under normal circumstances I'd have changed it, but I wanted to try it out and see how we could react and how the guys could make decisions based on the pressure and where the ball was being played.
"Once we weathered that early storm and got ourselves back in, it was a good test for this formation and, going forward, it gives us so much more."
The results over the Easter weekend leave Guernsey 10th in the Isthmian League Division One South with four games to go.
