Really? I've read mixed things about the high torque. It seems like its great for some types of uses and great for some other types of uses. I was leaning towards normal torque. But of course the added expense is minor so I could be swayed..
Depending how heavy the grass is I guess, i definitely could see the higher head speed working better with line on most grass unless extremely heavy or thick stems. In this case I’d want a grass blade not the string. Personally I would go standard model with higher head speed since the torque model is just geared down to get it.
I'm not chewing through particularly heavy brush most of the time. I feel like getting a unit with higher speeds and wider swaths is gonna do it for my purposes.
