Doepfer

Well, i want to have a modular.
I expect one about Doepfer but i have some questions about filters 
and oscillators:
1- My synths are MS20+SQ80. I like very much the comb HP12db+LP12db
But I hesitate with (2x) A121 and Analogue System (2x) RS110 and 
Analog Solution SY02 : what do you think about these filters ? What 
the plus and minor of them ?
2- My project is to have one Doepfer's Osc (A111 for Linear FM and 
Soft/Hard Sync) and  one Analogue System (RS95) : What do you think, 
by your experience of this combination ? Do any People try this 
solution ?

Thanks for your answers
