Brixham hit the ground running in National Three South West by winning 67-26 away to Old Patesians.
Hooker Chey Bryce and centre Tom Maclean both scored try hat-tricks as the Fisherman ran away with the game.
Matt Clarke, Kyle Browne (2) and Sam Thomas all got on the scoresheet as well with Ben Lovell doing most of the kicking. Clarke had one conversion.
Ian Morgan, the assistant coach at Brixham, said a combination of advance intelligence and proper preparation were responsible for such an emphatic result.
"We knew Old Pats liked to bully sides up front so were determined not to take them on in a forward battle," said Morgan.
"During pre-season we have been working on getting the ball away from the contact area as quickly as possible.
"That's what we did against Old Pats – and once we got to the third of fourth phase they were running out of ideas.
"Two of the tries Pats scored were down to our over-confidence in throwing the ball around. All in all, it was very satisfying."
Linford Brock showed off his pace as Barnstaple got off the mark with a 49-14 win at Oxford Harlequins.
The first half was nip and tuck for a while, but from 17-14 up Barnstaple shot clear.
There were tries in the backs for Ryan Carter and Will Topps. Lock Matt Gohl grabbed one for the forwards.
Kevin Squire, Barnstaple's director of rugby, said his new-look side showed up well first time out.
"Seven of the starting side are 19 or under – and ten of the squad we took were under 21," said Squire.
"It is the youngest side Barnstaple have put out since league rugby started – they are all local lads – and I doubt there is a younger one anywhere in our division.
"We wanted to run with the ball and get it out into the wide channels. When we played through the phases and at pace, Oxford just couldn't live with us."
Exmouth got off to a winning start away to new boys Malvern – just the job with a Devon derby against Newton Abbot coming up.
The Cockles' six tries in a 39-10 winwere shared between Tom Kill (2), Dave Bargent, Adam garner, George Savage and Glenn Channing. Andrew Powell landed three conversions and a penalty.
Exmouth had a number of new faces in this side, but head coach Jon Hill felt it all gelled well.
"I was particularly pleased with our attacking intent and the ability of our forwards to provide solid platforms to play from," said Hill
"We started brightly and counter attacked well from deep into our own half.
"Defensively we worked hard for each other and were disappointed to concede a try in the second half."
Newton Abbot left it until the final play of the game to grab the score which earned them a 29-25 win over visiting Chippenham.
Ed McGinley's second try, converted by Rob Avery-Wright, wiped out a 25-22 deficit. Earlier, Lloyd Radford crossed twice.
