It will be the perfect end after a season that has seen Tommy come to the fore with Glasgow and Scotland.
Tommy told the Evening Times: "It has been my best season for Glasgow. I have been with Warriors since 2011, but this season has definitely topped the lot for me.
"Obviously we have been very close in the last two play-off semis with Leinster at the RDS, and in particular in last season's semi, we felt that if we had taken it to extra-time we had a real chance to go on and win.
"But what we have to do is put all of that experience to good use this time around.
"We know the environment we are going into, we know the team we are up against very well, so it is not a journey into the unknown and we know that these games with Leinster swing on very small margins.
"In the past we have not had the benefit of the tight calls over at the RDS and we will be going there with a bit of a chip on our shoulder.
"But we are very much going there with the belief that we can get the win."
