So if you go single ply, 100% Titan. They also give a nice student discount which makes it the most affordable. If you are planning to compete USAPL they don't allow briefs in Single Ply so that is perfect. Do not buy titan single ply, no matter what anyone tells you.
If you go multiply, Boss by Titan is in my opinion, the best for non Canvas.
Canvas suit, the new Metal I have been wearing and is awesome.
Also for poly gear I recommend Metal. Ace would be more aggressive and Jack being less.
Metal Jack is not too aggressive, I personally am using a single ply katana and it works well much more forgiving and performs as well as a lot of multi ply shirts.
If you pull conventional, the new inzer fusion is pretty awesome.
If you pull sumo, the Metal King, is single ply front multi back and works very well. Don't forget in deadlift Suits, tight straps gives alot of the pop.
Titan Super Boss are amazing, like the squat suit the metal briefs are the same. Boss on Boss is very aggressive. Ace on Ace as well. Jack on Jack may be good too.
You need the following to be ready for a geared meet:
Briefs if Multi ply or single ply fed allows such as APF
Deadlift Suit if needed you can always pull raw to start.
Suit Slippers to get on
Shirt Slippers depending which you go with.
Hope this helps. I'd be happy to go into more detail and specifics if you have specific questions.
