i think i may have mis-explained what i mean by minimalist. i DO NOT mean minimalist price (although that would be nice.) i mean a minimalist design. i am looking for a plate that has:
1) steel
2) four bends in the steel
3) two 3/8th inch holes cut 11 inches apart down the center of the bent steel
4) eight 2 inch slots cut to accept a HOG harness.
this simple prescription was the primordial backplate design, and it used to be the ONLY backplate deisgn amongst HOG/DIR/GUE/UTD/WTF/BBQ cave divers. i am probably going to have to fabricate this myself. but if that can be avoided, what i am looking for
1) DOES NOT have multiple doubles bolt positions
2) DOES NOT have a "slot" to accept poorly-positioned tank bands
3) DOES NOT have slots to accept single tanks without an STA
3) DOES NOT have hand-holds
4) DOES NOT have a gazillion 3/8th inch "accessory" holes around the circumfrence.
i've heard stories of "YE OLDE CÆVE DIVERS" fashioning these backplates from abandoned road signs, reinforcing wings with slices of recycled inner tubes, and forging dive knives from chert. i'm not looking for stoneage, but i'm in the ballpark
