Questions regarding TranceTraffic torrent tracker

Hello everyone, I just went through the TranceTraffic
review and I would like to get some more information.

It looks like it's a decent tracker and maintaining ratio
is easier when compared to Waffles (where I am already
a member).

I would like to ask how is the tracker in terms of these genres:

* Drum And Bass/Dubstep/Drumstep
* Grime/Rap
* Progressive Rock/Metal/Metalcore

These are not the only music genres I listen to but they are the
most usual genres I go for. That said, I wouldn't want to just
get an invitation for the fun of it as I'm not a "collector". I always
aim for torrent trackers that might meet my needs. So answering
these questions would make me understand if TranceTraffic is
suitable for me.

I understand that it's very hard to get an invitation in DB9 so
that's why I went for Waffles and also considering TranceTraffic
if it's worthy.

Any information is welcome,

Regards,
loler

To answer my own question, after discussions with @Tassadar and @jaqenhgar at the chatbox,
it might be more reasonable to aim for redtopia.
