Screen protector for surface pro 11 and slim pen

Hi everyone. 

I’ve had my surface pro 11 for a few weeks now and have been avoiding using the pen much because I haven’t been able to find a good screen protector. I hand write a lot for work and don’t want any scratches. 

I got a tempered glass matte screen protector and I can barely write with the slim pen. It’s not great with responsiveness but it’s also really tough to write on. The pen barely moves and just gets stuck. 

Any suggestions that will allow me to use my slim pen properly but also protect my screen?
