The event is staged in honour of former STGC member Slater, who died of leukemia in 2008 and was the first person to win national, world and European honours while at the club.
It featured a number of top performers from the UK and club secretary Sue Mattinson said STGC were delighted to be able to attract such a high quality of acrobatic gymnasts.
STGC's gymnasts more than held their own throughout the weekend, deservedly picking up a host of medals.
STGC NDP gymnasts were in fine form, winning 12 medals in the Prep A and B grades.
The grade one men''s group top spot was claimed by STGC's James Martin, Jake Hewson, Hugh Baker and Leon Stoker.
STGC's novice women's groups of Amelia Gilland, Emma Costello and Estra Grant, Aaida Eghbal, Nadia Tiffin and Rachel Foster and Lucy Wilkinson, Neve Howe and Jasmine Allen claimed gold, silver and bronze.
For STGC's FIG gymnasts there was even more success with 17 medals in total.
STGC's junior (12-19) partnerships fared just as well, with women's pair Lucy Weir and Amy Cook winning a bronze and two silvers for three exercises and men's pair Lewis Ingram and Jake Phelan celebrating silver for all their three exercises.
