Hey Enrique! Ok so I think what you have said here makes sense, the best way when deciding to change equipment I believe is always to test both the different options and give each of them time to see you get on. This is the only real way to see if one feels more comfortable than the other and which shots feel easier or harder. Make sure you give both a fair test and in the end you will get a feeling of which set up is working the best for your game.
When I changed my rubbers recently I tried my favourite shots with each one and tried to see which felt easier and which one I could get the best quality shots with. To me it sounds like you prefer the thicker sponge for almost everything apart from the knuckle ball shot, so maybe it’s a case of just training that shot with the thicker sponge and seeing if you think you can get comfortable doing it, and also how important that is for your game compared to the other advantages of the thicker sponge.
I hope this makes sense, let me know if you have any questions. Dan 🙂
