Wings Visser and Jones, and young full back Brown, has scored 10 tries between them in Edinburgh's match to an historic first Heineken Cup semi-final and coach Michael Bradley has built his
"The Edinburgh back three are quite something and will pose a massive threat to us. We are all aware, and me in particular, of how big a threat Tim Visser will pose to us," admitted Trimble.
"I hardly took my eyes off him the last time we played against each other. You know that if you don't watch his every move, just give him a split second, then he will punish you.
"We know it isn't going to be easy. The great thing about this semi-final is that both teams play exciting and entertaining rugby. I just hope the occasion doesn't get the better of either team because this game has all the makings of being a great spectacle.
"There is a great buzz about this squad and I love playing for Ulster. We might still be relatively inexperienced in Heineken Cup rugby terms, but there is no better experience than beating Munster at Thomond Park.
"That victory, and reaching the quarter-finals last year and this, just shows how far we have come. There are a lot of teams that win their home games, but you have to have the ability to go away and win on the road to do well in the Heineken Cup.
"We have always known we are capable of something big and now we are on the verge of reaching a Heineken Cup final. We feel we are going places and we are starting to turn a few heads with our performances and results."
There will be almost 40,000 Ulstermen crammed into the Aviva Stadium hoping for a similar result to the 1999 Heineken Cup final in Dublin when Ulster beat Colomiers to become the first Irish team to win the trophy.
"Jonny Bell, out defence coach, keeps reminding us about what happened in 1999 and there is no doubt there is something special in the squad this season," added Trimble.
"There is something special about playing club rugby and playing with your mates. I have grown up with a number of the Ulster players and I was in the same Ulster Schools team as Chris Henry and was coached then by Brian McLaughlin.
"That's why the Heineken Cup is so special. The passion, desire and determination to do well with your mates is very powerful and makes people want to succeed.
"There is a huge prize at the end of this game for whoever wins and I'd love to reach a Heineken Cup final and have a shot of doing what Ulster did in 1999. I went to that game with my Dad and I can still remember him telling me, 'Remember this son because something similar might not happen again for a very long time.'
"I never thought then that I might one day be playing on the same pitch the next time Ulster had a chance of reaching a final."
