The Active Starburst on the 201 is certainly a lot harder on string then other response systems. However if you use the adjustable gap and have it set to a wider gap and use 100% Poly string, you’ll find the string will last a fair deal longer. Also make sure you have clean hands when handling your string, and if possible avoid humid areas.
There are plenty of ways to “mod” your 201 to lesson the Active Starbursts wear on string. A lot of people have removed every other prong. One guy I knew removed one side completely. Don’t know how effective that was, but he liked it. I’ve also known people to just put a response sticker over the Active Starburst, like Duncan Silicone Stickers.
Your best bet may just be to move on to another Yo-Yo. Don’t get me wrong, my 201s are still a lot of fun for me. But they’re by no means going to carry you far.
