I've logged more than 10 dives ever since I switched to backplates and I believed I have fine tuned my rig except for one major thing. I cannot seem to position the tank so that my head would not hit the reg when tilting my head upward on a horizontal swimming position. I have adjusted the STA, back plate, webbings a lot of times already. I figured that the problem is the dual cumber bands on the STA which prevents me from sliding the BP further up the tank because the top cumberband will no longer grasp the tank. To solve the problem I thought of drilling another cumber band slot on the STA. When I went to my LDS, behold! they have an aluminum STA that only has one cumber band slot position at the center of the STA.

With the single cumberband STA I have more room to adjust tank position on the BP.
The single cumberband I think is common to many jackte style BCs and works quite well. I have not yet tested my rig with the new STA, but I was wondering.. is there is any functional reason why all (?) BP set ups have 2 cumber bands on the STA?
My LDS said that they came up with the single cumberband STA because they had problems selling their Diverite BCs (with the plastic STA) to some people who cannot seem to position the tank on the right spot on the STA.
