I might be purchasing a lawn dethatcher for this fall. I have a choice of what type of blades and what style spacing I can have. Which does everybody run and how do you like the performance? I have rented a thatcher last season and I have no idea what type of blades it had on it, I just know about the height settings. My choices are: Flail-Type 1/8" with 1" spacing Fixed-Type 1/16" blades, 1 1/2" spacing; 1/32" blades, 3/4" spacing; 1/8" blades, 2" spacing **note, the above specifications was from the ryan website.** Heres a link to some specs about the machine. http://www.ryanturf.com/products/specialty/ren_o_thin/index.html Thanks in advance for any help!
