So I've always just used the echo bottom of the line straight shaft which is the SRM-225. It's like a 21.2cc engine. All the other guys use like a 260 or a 280 I've noticed. Honestly I always stuck with the smaller one causes it was cheaper and not as heavy. When it's 100 degrees outside it makes a difference. These new echo's are already heavier than the older grey models from what I noticed. My 225 has always had plenty of power unless the grass has like 2 weeks of growth and it's been raining.
What's the benefit of the bigger models? Do they last longer? Everyone I see has the guard taken off so they can spool out 2ft of line. That's the thing about the smaller ones is you can only spool out an extra inch or so more, otherwise then you're overloading the motor.
