.105" Black Diamond Trimmer Line (217 ft.) Large Clam

No sure what the line size you need. I think that there are other line sizes, you will have to check it out.

I find it easier with the echo cross orange line and having just around 3 inches worth of string and having a low or slow rpm

To my knowledge, this trimmer line can be used with any trimmer as long as it calls for .095 trimmer line. It goes by the size of line that the unit calls for.

The answer would be yes, but just remember if you use a thicker line than what you have used before you may not be able to go back to the original line of lets say .80. The smaller line will be depleted at a very rapid rate.

Yes

I’ve tried to use this twisted black horse crap...been an echo man for years but this line breaks easy and isn’t any advantage. Old echo .095orange still mashes all others.

.095 the engine will spin higher RPM could have leaned it out with an air leak in the carb or dirty fuel filter. You can also pull in air around the crank. Any air leak will lean it out scuff the piston ring on the cylinder wall. Most times you can hear and sometimes smell it leaning out. You can not keep running the engine or major damage will happed.

It is almost as thin as .80 line. But depending of Wich Ryobi you have. Most gasoline Ryobi's are .80. I'm pretty sure it won't slow it down. But still. That's just my guess. I haven't tried in a Ryobi. Not sure if it will fit

Was very impressed! Some wif the best trimmer line I have ever used! Really tough, used it in brush, honey suckle, thick ivy. Just mowed it down!

Sorry, I don't know. The Black Diamond is very tough and cuts very well. I have never used the Cross Cut.
