Why not together? Cabaser and g2g i think...
Goal? Add muscle mass 
As lean as it possible ( depend of diet... yes i know :-) ).
I'm on test/deca right now, and I'm constantly holding water, bloated, and way stronger. I'm sitting around 9 or 10% bodyfat (my diet is very strict year round) but with all that water I hold my midsection looks like I'm 12%+ lol. Arms and legs have veins(ish) and striations, but midsection looks 12 weeks out haha - I also have to piss every 20mins
. I just think that if you're gonna run deca there's no point beating up your body with tren. I'd save the tren for when you're dieting. You'll bloat on deca anyway, the tren is good for having that hard look once you're under 10% bodyfat and not holding a lot of water, if you're trying to gain you will also gain a little fat, so why not just stick to deca and take full advantage of it? Then switch to tren in the spring and cruise into the summer season looking like a fucking god.
Just my $0.02
