The final of the Pembrokeshire Rugby Knock Out Cup has jogged around again with Narberth and Whitland appearing in the final as old rivals eager to put one over the other.

But unlike other recent years the Borderers have gained the ascendancy for this campaign and will be red-hot favourites to take the cup home.

So just where will the cup be won or lost? Telegraph Sport has tried to pinpoint just where each side's strengths and weaknesses lie.

Tight Five Whitland seem to have a real advantage in this area because they have strength in depth, with cover for every position and a determination to play for each other that has seen them win some matches this season through sheer doggedness.

They have three possible hookers in Aled Harries, Jason Evans and Dafydd Lewis, plus props Andrew Morrillo, Gareth Williams, Romeo Colella, Alun Davies and Alan Proctor.

It is a wealth of riches compared to Narberth, who have Alan Phillips in New Zealand and so must rely on Martin Bowen, Fifitapuku Faletau, Siese Navunitale and Adrian Chiffi to battle on in the front row.

The Borderers have Raff Williams as their possible player of the season in the second row, with Carwyn Davies and Graham Hartt as others who can win key lineout ball. The Otters will have skipper Emori Katalau, a Fijian international on many occasions, leading by example and trying to win the lineout battle alongside Jason Jennings and Dai Ebsworth.

Verdict: Narberth could really struggle for quality possession, especially in the scrum.

Back Row More evenly balanced perhaps as Narberth's player of the year, Lewis Wood, will have support from Matthew Davies and Jamie Bohata, who all like to use the ball well.

But Whitland have trump cards in skipper Randall Williams and former captain Phil Morgan, both expert ball winners and killers of opponents' possession, with Celt Thomas and the rapidly-improving Ryan Michael as their flyers' around the fringes as well as being good ball-winners in their own right.

Verdict: Again Whitland have the edge, with a height and weight advantage, but without restricting their pace or handling qualities.

Half Backs: Whitland hold a clear edge in experience in this department, with Andrew Jenkins as another player of the season candidates and Aled Davies in good form with the boot as he plays against his former colleagues. Jenks' is like a ninth forward and covers superbly while Davies can set his backs in motion and regularly scores tries as a bonus.

Narberth must decide on Mark or Andrew Davies at scrum half and Tom Lewis or Wes Pooley at fly half. Lewis back from injury and is a long-distance kicker so that could gain him the verdict at No 10 while either Davies boy can slot in alongside him at half back. If they can get enough possession they will look to run the ball as often as possible.

Verdict: Another plus area for the Borderers!

Three Quarters; Whitland have strength in the centre as Gary Evans, Eifion Roberts and Lee Glanville are all strong tacklers and straight runners, with Jack Tremlett, Dion Thomas and Will Davies looking to use their pace wide out. Glanville or Davies is likely to play at full back and there is a solid look about the Borderers in attack and defence.

Narberth will have Neil Davies as a focal point of their three-quarter line alongside Steve Martin, Rob Irving, Mike Georgiou, Mark Davies if he's not at No 9, and hopefully Matthew Davies.

Verdict: Narberth can gain parity in this department, but only if they have enough ball to utilise!

Full Back: Lee Glanville has occupied this spot over recent months and is now back to something like his best with his sound positional sense and direct running.

Sion Brace is a must for Narberth because he is an adept counter-attacker as well as being a sound defender and will look for every opportunity to break out from deep positions and support other moves.

Verdict: Narberth will need lots of involvement from one of their key players if they are to have any chance.
