Thanks everyone for their input! My silky ibuki is in the mail! I picked this one because it sounds like it rips wood apart. For those who were wondering, I'm going 2 be topping and removing my nighbors 100' firs this weekend so the diameter at the top is aout 8 inches. I know its going to be a grind with a hand saw but these three trees will be the first I've ever removed with climbing gear (also in the mail) and I know ill be more comfortable at 100' with a hand saw rather than a chainsaw! I'm going to hoist up my chainsaw after topping these monsters and put the hand saw away. This brings up another question I have: WHEN BLOCKING DOWN, SHOULD I DROP 10 FOOT SECTIONS (to get out of the tree faster) OR DROP REGUALR "ROUND" SIZED PIECES??? Please take into consideration my limited expirience with spur climbing...thanks!
