Hey Colin, thanks for the response.
I end up going to one of the usual suspects (Trew in Vancouver BC) and they helped me out greatly. And I got the 607. The FP33 fits really nicely and it goes well along with the 722. Yes! the wireless pouches are a really nice add-on. It was great to have the front pouch available for extra batts and bits and pieces, instead of being filled with he Rx.
Next buy: a harness!
