Hi, I am going to get 40D in addition 350D I had. I already have Tamrac Velocity 8 now and am looking for either op-tech strap or another bag to carry 2 bodies with 17-55 and 70-200F4 attached. My Velocity 8 can hold 40D with 17-55 attached and 350D and 70-200 unattached.Somebody recommended Crumpler 6/7 million whick can hold my 2 bodies with lens attached. I am also thinking about getting op-tech strap Pro Loop to carry one and keep another one in my Velocity.Because none of my local stores have them, I can not compare these 2 solutions. Does anybody have experience with them?? Which do you prefer?thanks a lotJJCPA
