Which slingshot board?!!

I need to decide weather to go for a 2009 recoil or a 2009 response

About my riding-

I'm a beginner intermediate
I have a sacked out I/O so smallish wake
I also regually ride behind my buddys X2
I don't ride cable as there are none local
I ride on the sea and it can often turn choppy (I have read that of the 2 the response has more flex so it it's a smoother ride in chop.

I need to decide asap because I have to order today.

Thanks guys!
