Trimmer/Brush Cutter

Occasionally have some high weeds/woody brush to cut, but not enough that would warrant a stand-alone brush cutter. Looking for recommendations on a gas string trimmer good enough to handle a brush blade. My current Stihl won't handle a blade. Was eyeing up the Echo SRM-2620 or 2620T. The latter high-torque would appear to handle brush better but would the 2620 be better suited, as I do mostly grass?

Any other brands/models y'all would suggest? TIA
