i have both blades and tested fastarc g-1 on forehand and rakza 7 soft on backhand
virtuoso feels more direct as in the ball goes where i want it to go and only slightly head heavy
acoustic feels like it has insanely high throw i kept sending the ball off the table before changing how i hit the ball compared to the virtuoso and the acoustic is way more head heavy compared to virtuoso
for me and my playstyle i find the virtuoso easier to use and it always does what i want it to do but i play close to the table and have very direct shots if you play about mid distance from the table acoustic might be better
i have been on an EJ journey to try and find a blade i like more than the virtuoso off- but i find it really hard to top here are some of the blades i've tried but keep going back to the virtuoso
viscaria (feels pretty good but a just a tad fast for my liking)
liu shiwen zlf (a bit too fast for my level but solid)
nittaku acoustic (high throw and head heavy)
victas firefall fc (feels weird different than any blade i've used before)
gambler touch (does not feel good to me)
gambler hinoki (too fast)
7 ply clipper clone (this one was also pretty good imo)
appelgren allplay (smaller than average head size)
galaxy w6 (it was head heavy from what i remember but it's been so long since i tried this i might need to try it again lol)
touch 01 (solid budget option from colestt!)
as you can see money is but a number to me lol i enjoy trying everything in a search for my favorite blade since i've already found my favorite rubbers
