Band stretch/size for custom speargun

Im in the process of building a speargun that I intend to use for reef/midwater fishing for grouper, pargo, AJ, wahoo, etc down in mexico.

The gun is ~170 cm overall length. I will be rigging it with a 180 cm 7.5 mm shaft. It should be similar in size to a 140 cm euro gun.

The shaft I have currently have two tabs, so I'm looking at running only two bands

I intend to use 14.5 mm small ID rubber, with a wishbone length of about 4 inches.

The band stretch from the center of the band slot to the tabs is 52" and 55"

Using some formulas posted on the board, I've come up with band lengths of 29.5" and 31"

Just fishing for opinions/feedback concerning band thickness, length, number of bands, etc....
