Sure!

Thick picks are great for being very sturdy and allowing for extremely quick playing, but they can also act as a crutch and hide bad technique since they can just smash through strings. It’s like playing on easy mode so you don’t notice all the sub-optimal stuff you’re doing.

Those super thin nylon picks, on the other hand, are really floppy and not great for fast, precise picking. However, you can absolutely still play relatively quickly with them as long as you hold them proper and just use the tip. It’s hard mode to make you really think about what you’re doing.

The trick is to be able to play up to around 90-100bpm with the floppy picks to help you build good habits so that you’re getting the most out of the bigger, stiffer picks.
