Don’t be afraid to leave the fruit salad out altogether and actually taste the gin. Equally don’t be afraid to mess around and find the right addition for your gin. It’s a highly personal thing but some things just work together. Google for whatever gin you have and give it a try.
Plenty of ice and make sure the tonic is cold.
For a tonic alternative the Fentimans Rose lemonade is really great.
