What do you guys think about having 1 x 20mm rubber on a RA Tuna 100cm? I'd much rather spend less time loading in the water. I'm not sure how the 7.5mm spear will shoot with this setup. In Australia, we shoot 7mm spears with a 16mm rubber and was curious what you guys think
 
I use a 16 mm or 17.5 mm band with a 6.5 mm shaft. For 7 mm I use 2 X 14 mm bands, although 1 19 or 20 mm band is common. For a 7.5 mm shaft I'd go for 2 X 16 mm bands. Using less band will give slightly less power, but probably a little better accuracy.
As long as the 20 mm band works and is accurate you should be fine.
