I wanted to get a little insight from some of the MTT grinders here. What's the fastest blinds you'll consider playing?

When I started I was playing the Turbo SnGs and I liked them. And I did ok in them. But once I learned about the variance involved with those speeds I've been trying to stick to regular MTT. Those seem to be mostly 10min blinds but I played a 12min the other and didn't really like it, although I did well.

I'm looking at getting into some that are 8min increases but I'm worried it might be too fast. So, just curious what you guys try to stick to?

The site I'm on doesn't list 12, 10, or 8 minutes MTTs any differently. They're all listed as regular speed.

Thanks
