First of all, thank you! I have some main rackets that I will always bring in my bag, such as DZS, 100ZZ and 99 Pro for singles, 11 Pro and DX10 for doubles. I use them for serious games because I’m used to them with my timing. And I try to have them at the same weight and string setup. (My personal setup is 3U, BG80 Power @28x29lbs). You are right about using different rackets with different specs would definitely affect our timing. For fun games with my friends or for practices, I rotate to other rackets as how my mood that day goes. So it doesn’t really matter if I need to adjust my timing or mishit the shuttle a bit. Hehe I’m glad that my input was useful for you. I didn’t play much with the Axforce 70, but it felt unmistakably similar to Astrox 66. Decent racket for when we just want to have some fun, I think. And the paint is nice too!
