I find that with the 3/0 Flying Dutchman new spiral, and #3, 5, and 7 ultra reverse i can cut just about anything i am going to cut...Just my 2 cents worth !!
Welcome to the Village Bob !....I have the EX 21 and love it , little to no vibration.....it is on a factory stand and has cut like a dream since day one(when i did not have a clue what i was doing). good luck getting it squared away!
