I think that Sweden Extra is too slow for Rakza 7 Soft. Instead on backhand go a little bit thinner if You want a slower pace. So 2,0 on FH and 1,5 - 1,8 on BH.
Rakza 7 Soft is a really slow rubber and Rakza 7 although not slow it's not super fast either. Look at one of Dan's later review videos...
