Looking for Doubles Tips

Me and my friend just started taking doubles somewhat seriously and we find it really fun. Just looking for some tips on how to play it versus other modes (I play a lot of slayer) and ways that other players have found success to win more games. Feedback from all skill levels would be great, thanks.

Doubles is all about taking power ups and power weapons first along with LOTS of stealth, I kinda hate it, I prefer the chaos of FFA and Slayer, or really any 3-5 player team modes.

Stick together. Stay hidden until you have the advantage.
