Utilizing curve/sidespin on heavy balls?
After spending the last year at plugging holes in my groundstrokes, I have developed a pretty decent baseline game with a balanced heavy driving FH and a really heavy 2HBH. I was hitting really well the other day during a 4-hour session, and noticed that my opponents (people who hit with me a lot ) were not just clipping under the ball a lot but also sometimes shanking towards the tip
of the racket (and twice total whiffs). After the initial couple hours, my buddies said that the balls were jumping up from the topspin, but also seemed to have a curve or kick wide. For instance, they said that the 2HBH out wide seemed to curve away from them. They also said that when I hit a down the line shot with a buggy whip follow through, there was an odd side spin that made it hard to catch in the air and also off the bounce.
This leads to my question: how prevalent is sidespin in heavy balls? And if it is prevalent, is there a way to manipulate it?
For final context, I am 3.5ish who generally takes fast cuts and have a variable takeback depending on the ball/shot. I like to stay quite low and spent a lot of time in the past 18 mos. on weight transfer and spacing. Balls are heavy. Racket is v8 Vcore 98. Strings are Super Toro + Enso Pro.
