I'm a buy once cry once guy, you've nudged me to my senses and the 300g2 it is. Now comes a few overtime shifts@WonkyWapiti I agree with Jenyphur. I currently run a 170 and a 300g2 and unless you just don't have the room I would go 300 all day long. The 170 is nice but it has no room in the cabinet and a 3ft tank vs 2ft just gives you so much more room in the display.
