Harder forehand loop

Hi alois

i have finally gotten my forehand loop under control where i can make it very consistently. I can put it where i want, get decent spin, and make it confidently. 

I found that my opponents are returning it too easily recently. Even when i swing as hard as i can within reason and maintain good technique, my opponent still returns the ball often and low.

i recently got beaten badly at a tournament not because i failed to make the forehand, but because i had no answer when they returned it. This was even more discouraging when they were overpowering me with their spin and speed. 

I dont think the problem is my strength as I am stronger than many people who put more shots away than me. It may also be that I am hitting with speed but not enough spin to force an error as i hear my opponents complain about the ball being dead when it goes into the net. 

At the tournament, i would make an error on their foreland loop due to a lot of spin mainly. Even when I tried placing the balls in many different places, they still had no problem making a good return.

What should I do? Some people say that I may be trying to make my contact too spinny. If I try to hit flatter, my control will definitely decrease. I dont know how to combine speed and spin to make a powerful shot. I am usually good about getting one or the other. Please help. Thank you.
