Alright I have a few suggestions for the TTT server.
1. More rounds per map. Seriously I have bad internet. So it takes me about 1 minute to load. Then I can only play like a few minutes cause there are only like 2 rounds left.
2. More weapons for detective and traitor
3. The ability to salvage a scanner off a detective.

The first one is a problem on your own end.

I agree with the second one.

The third one would be interesting to see.

If you're having problems downloading the maps just download them from the internet and put them into your garrys mod maps folder so you don't waste any time during the game, also this should't really be an issue because most of the maps are CS:S ones.
