The step-up in Ulster's form this season has been evident for all to see - they won their first 11 games in some style and so unsurprisingly Ireland head coach Declan Kidney came knocking.
Few would have expected quite so many players to be leaving however and as a result, the wheels have threatened to come off.
A disappointing end to their Heineken Cup group means they will be heading to Twickenham for their quarter-final rather than staying at Ravenhill while Glasgow Warriors' superb form has seen them move top of the RaboDirect PRO12 table on points difference.
In domestic action, Ulster have won just one of their last four matches with Treviso stealing a draw at the death last time out but Trimble has continued to impress, scoring his sixth try of the season against the Italians.
This weekend they head to Edinburgh, looking to get back to winning ways against a side in freefall but about to begin a new chapter under Stevie Scott and Duncan Hodge.
But Trimble is confident his side can put their two-pronged assault on silverware back on track in the Scottish capital.
"If you look at the season I think we're going great at the minute and I wouldn't want to be anywhere else. We're playing really good rugby at the minute and we're going well, it's a lot of fun," said Trimble, who agreed a new contract this week.
"We've a good shout of doing better than last year, which saw us get to the Heineken Cup final and I'm really looking forward to that challenge.
"Edinburgh is a tough place to go, Murrayfield is quite quiet and there's not as lot of atmosphere and it puts you under a bit of pressure to develop that buzz yourself but hopefully we can get things right."
While Ulster will be hot favourites to get back to winning ways this weekend, looming large on the horizon is a clash with a resurgent Leinster side, a match Trimble admits he's already relishing.
"Just around the corner and maybe in the back of our minds a little bit is the game against Leinster," he added.
"There's provincial rivalry and the intensity is going to be through the roof. You always raise your game a bit more and there's probably a fear of losing to them more than a desire to win and that spurs you on that little bit more.
"And then we want to use that to go ahead into the quarter-final of the Heineken but we just want to get players back from the Six Nations and make sure we've got that buzz that we need."
