I really like that windsplitter and it's a great price. But I read the description and the windshield pouches/bags are not compatible. I guess the zumo 660 would fit. Did you try it with the bags/pouches?
I have the 10.5 Windvest. Works great up to 60 mph then all hell breaks loose. I'm 5'10".
Just ordered my third attempt. 10" Freedom Shield. May just need some hard lowers but I got pounded with the Windvest.

I did not try anything with it, I never mount bags until I decide I'm keeping the shield I find they is a higher chance of damage if installing a non-needed part while testing.
Sorry I can't answer.
