Guernsey RFC head coach Jordan Reynolds says they are learning from Cornish Pirates during the Championship side's week-long stay on the island.
The teams announced a link in 2013 and will play a pre-season friendly at Footes Lane on Friday.
"It's always easy to learn off someone that's failed and trialed things before," Reynolds told BBC Guernsey.
"We can look at where they've failed and where they're succeeding. It's fantastic to have that link."
Guernsey play three levels below the Pirates, in the National Three London league.
During their stay, Pirates coaches and players have taken several training sessions to help their hosts.
"We've had Gav (Gavin Cattle) taking the backs for multiple skills sessions, Paves (Alan Paver) looking at the scrum with us, their captain Chris Morgan took a line-out session and Ian (Pirates boss Ian Davies) did some breakdown work for us," added Reynolds.
"We're pretty honoured to have that opportunity and link - hopefully it can keep on blossoming.
"The side we put out against the Pirates last year wouldn't compete against the side that we could put that this weekend. We are a changed team."
