"Banwen are certainly the strongest team in the division and definitely the best side we have played against," said Chris Hansard, the Mumbles vice chairman and team manager.
"I really don't think that anyone can catch them on their current form but we will do our best. "I'm optimistic of achieving a promotion place but we are taking it one game at a time. We have got matches against Bryncoch and Maesteg Quins coming up and they will be crunch meetings that will determine our season."
Banwen went on their merry way with a 23-16 win at Nantyffyllonwhile Maesteg Quins held onto their second place with a 27-24 win at close rivals Kenfig Hill. Bryncoch moved onwards after a 31-15 success over visitors Brynamman.
Seven Sisters slightly improved their position after beating fellow strugglers Trebanos 28-14, and Skewen won 28-14 at Glynneath. Tries from Justin Loveridge, Mark Bilenki and Rhodri Pretty eased East leaders Senghenydd to a 22-6 victory over Pontypool United.
Brynithel remain second after coming from behind to beat Newport Saracens 12-8 with second half tries by Gavin Hayes and Tony Jayne. Llanishen stay third with a hard-fought 13-5 success over a defiant
Newport HSOB with Andy Howell crossing for the Lions only try. Abercarn's 24-21 victory at Cwmbran could ease their situation near the bottom of the division.
Gilfach Goch's title hopes have been put on hold in South East after bitter rivals Treherbert edged home 19-18 to take over top spot. As the winners also have a game in hand on Gilfach it was one the home side had to win.
At the other end of the table Tylorstown moved above Taffs Well after their 15-11 victory, Ynysybwl beat Pentyrch 18-13 and Nelson were too strong for bottom club Barry to record a 19-3 win.
In the West, Kidwelly gained a fine 25-10 win over Haverfordwest and Pontyberem stay top after a hard-fought 16-5 success at Gorseinon.
