Hi
I recently broke my m80 spring (well I didn't my friend did) so I thought I schould order a new 1 (thought I only needed 1 as other is still bloody solid) so I did not releasing that it came as two springs I thought it was only 1 so now I'm thinking schould I get 70's as I was struggling to get any height atall as I only weigh 8 stone
So what schould I do and is there any way pro jump can help??
