Xilinx GTP_DUAL: wizard or code ?

I am using for the first time a Xilinx RocketIO module (I have years
of FPGA experience though); normally I prefer to explicitly write on
my code all the instatiations.
Manual UG196 says:" The RocketIO GTP Transceiver Wizard is the
preferred tool to generate a wrapper to instantiate a GTP_DUAL
primitive."

Any experience and advice about coding vs wizard in the case of
RocketIO ?

My application requires to use the GTP for a simple but non-standard
protocol (8b/10b with a custom packet).

Its not just about instantiation. More than that, choosing the right
values for the parameters as GTP has large number of parameters.

GTP wizard helps you to setup the required values for parameters based
on applications. Eg. SATA, PCIe.

However, from my experience - Some parameter's default values from GTP
wizard may not work good for you. Need a code chage in this case.
