Hacksaw Question

[CUTS LIKE A KRIS]

So I should be able to get downstairs sometime in the next week. I have not been to my workshop for 5 months so I reeeeeeallllllly want to get to work on something. So here is my question- Which of these two blades is best to use in my high tension hacksaw (that I got just before hurting myself) 18tpi Lennox bimetal or Westward Bi hard Cobalt blades? I have both but don't know which is better, and have heard many discussions on drill bits and belts but nothing on hacksaw blades. I am going to be cutting 3/32 O1 & CPM 154CM; 1/16", 1/8", & 1/4" O1 (cause thats what I have).

Any help is appreciated, if no help is forthcoming I'll just use one, then the other, and decide which I like better- I just thought I'd get professional input first.
