Depends, are you hitting stuff?
With two 16mm bands, a 26" and a 28.5", one on your pursuit helper fin tab and one on your secound fin tab, the recoil is too strong for me to tell how bad I am missing lol.

Diesel, in this case shaft overhang is not your main consideration. I believe you need a gun with more mass, and/or longer bands, or bands with a smoother pull. It's difficult to become accurate with a speargun when you flinch every time you shoot it. Power is of no use when you can't hit the target.
I use Riffe Godzilla bands...the yellow ones. To be honest, I cannot pull neither of the bands on the last tab, and I am about 6'4" and 265 lol.
Sounds like you're overpowering the gun then and your issue is not shaft overhang. I think everybody overpowers their gun in the beginning, I did.
I use to use a single 19mm 32" band, and the gun was underpowered significantly. This is why is use two 16mm bands between 26 and 28 inches. I might just get another 28.5 band and take off the 26.
I also just installed a new Buechat Pacific reel on the gun, so those cuddas are going down sunday lol.

Diesel, there is a relationship between band, shaft & gun mass…to balance the outcome for accuracy…just play around with band stretch till you get the least recoil with the shortest bands.
This is how I would do it.
- Calculate band length according to the regular 3:1 stretch ratio and stick to 16mm bands….at this -stage, it doesn't matter what brand of rubber you're using.
- IMPORTANT….for wishbone, go for the Italian style wishbone where you have a knot at the end of each rubber and a separate cord attaching both ends of the bands (if you need help making this knot let me know).
- Tie the cords with the end knots so that the total length of each wishbone, from rubber end to rubber end is no more than 12cm (assuming you're using 2 Bands)
- Test your gun in very stable conditions…I use a plastic water bottle in a pool.
- If you miss after several trials or gun is shooting a bit low, replace the cords and this time increase cord length so that the distance between each rubber end is 14cm…i.e., go in increments of 2cm.
- Depending on your gun mass and shaft size, at one stage your gun will shoot smoothly.
The Italian knot makes it very easy to change the cords on location…actually, I would prepare several different cord lengths before testing.
Good Luck
