Llanelli are aiming to lift the Welsh Cup for the fourteenth time when they face current Cup holder Neath on Saturday.
Buchanan said, "We have confidence in the starting line-up that did so well to beat Aberavon in a pulsating semi-final and we wanted to reward that team with selection for the final. Only Dwayne Eager has worked his way into the 22 after impressing of late.
"Going into the match, this is definitely a game where both teams have a 50% chance of lifting the trophy. We both have a strong history with the cup, Neath being current holders and we at Llanelli have such an affinity with the competition as 13 times winners.
"There are never any easy games against Neath and there hasn't been much between us in our games this season. One thing is sure, we will certainly have to be on our best form to bring the Cup back to Llanelli, but that is our clear aim, the cup means a great deal to the players, the club and the town. Our season would certainly be seen as a successful one if we can bring the cup home on Saturday evening."
Current cup holders Neath have named a starting line-up with just one change from the side that started against Swansea in the semi-final, with wing Dave Evans coming in ahead of Wayne Mitchell.
