I think you asked me this question in PM but I forgot about it... terribly sorry bro. Anyway here's my thoughts. The 2217 from my experience has very sufficient flow for this size tank. if you need more flow later on, you can always add a powerhead. Anything with higher flow would mean plants laying on their side against the substrate. I still have that problem with some weaker stems such as Rotala sp. 'butterfly' and 'macrandra'. But, that's also because I chose to run an added powerhead.
I'd jump for the 2217 if I were you. I've had mine since I started planted tanks and it's been running perfect.
haha Glad you like it bro. I'm never happy with my own stuff... never. Lookin forward to seeing your own 40B up man. Lemme know if you need help. Oh... are you also a member of SFBAAPS... just noticed your from the City.
