I do this too, but it has it's limitations. I was recording last night 
in a 4mph breeze. Not steady but gusty. No cover except the car and my 
body, which were not enough. The M/S setups using the furry cover did 
pretty well, the SASS, for which I only have Crown's wind cover needed 
some help. I need to sew furry covers for them. I'm also thinking about 
sewing close fitting sleeves for each mic inside the zeppelins in the 
M/S setups out of elastic speaker cloth. A ultimate layer of protection 
from what gets in. That may make it less often I have to use the furry.

There is a difference between a rycote zeppelin and the Sennheiser ones. 
The lining of the zeppelin in the rycote is kind of like flannel, more 
wind stopping than the very fine screening that Sennheiser uses.

The rycote cover for the telinga is quite good at handling the at mic 
sounds. You can get up to where the wind is buffeting around the dish 
before having problems. It would be easy to make as it's just soft 
fleece cloth that's got a elastic in the edge and fits over the dish 
opening covering the mic.

This is a separate issue, and I often don't worry about recording that. 
It's part of the natural sound.

You have seen the ones on the M/S mics I use, which are standard 
Sennheiser gear. The problem with crossed shotguns is it's a big kit. A 
lot to enclose. I'll have to design a frame to support it, fit that with 
the plastic canvas craft mesh, line that with a fine windblock layer, 
then sew a furry to go over that. Doing that in a simple, practical way 
is not going to be easy. It's actually one of the reasons why I like M/S 
over X/Y setups, a lot easier to enclose in protection.
