hello - on a recent trip to coz (with my new zeagle bc - which i love), i experienced on, several occasions, (before entering the water) the tank slipping thru the bands; almost like the straps weren't long enough (we were using 120 cu.ft.steels); i have loaned my bc to a friend so i don't have it here now; but i have a question - how long are the tank straps on the deluxe tech express excluding buckle? if i wanted, i suppose i can replace them with straps that are a few inches longer but i was just curious as to the exact length of the straps supplied with the bc; thanks
