That's what I have now. It works pretty well, but I recently had some whistling from the wind through the suspension of the Rycote mount, and the string with toggle on the furry that goes with the BBG has a habit of getting loose and banging against things and making noise. Last but not least, the the mic tends to get rotated/moved, and sometimes things snag the cable. In short, it works for blocking the wind most of the time but is fiddly. I hate fur. It's always getting caught in the zipper of whatever bag I put it in, unless I take it off the basket and turn it inside out but then it's a few minutes of getting it back on.
DanieldH - I'm making recordings for my own use, usually (but not always) on outings where collecting sound isn't the primary purpose. Ambiences, the sounds of vacation, simply interesting stuff. Not sound for film, ENG, etc. Most of the time the mic is stationary or handheld, not being moved much (as it would be for booming on dialog I'm guessing).
I have a BP4025 which is what I use 90% of the time. I also have a BP4029 that I'd like to use more often, but it won't work with the BBG I already have, and the BP4025 is too heavy for the suspension in the Rode blimp the BP4029 lives in. Since sound is usually secondary two blimps is one too many.
So, the WS3 would probably fit both mics (not ideal for the BP4029), would probably work pretty well, but will probably need fur most of the time and changing mics is probably not as easy as the Cyclone. The cyclone is larger, maybe less fiddly, and the difference in spec between both mics is just the suspension. The cyclone does not come with a hand grip, which is a bit of a minus, but I can get an accessory grip.
