Best Cut Off Wheels And Sawzall Blades?

I went to Lennox website and this 210617614GR LENOX Gold® POWER ARC CURVED EXTREME METAL CUTTING RECIPROCATING SAW BLADE might be the way to go:

Interesting automated side by side comparison with a Milwaukee which did 13 cuts in ASTM A36 mild steel plate and the Lenox which did 68.

Only one amazon review by R. Yee:

"Best blade I found to cut metal with saw saws (sawzall?) use cutting oil and go easy this blade will last longer."

If I buy the blade and use it, I will report back. But after looking at my pictures (uploading them made me look at the project order a little differently) the current height of the A-frame is perfect for sitting on a stool and grinding off the existing hitch coupler. So I think I will leave the A-frame to trailer welds in place now, grind off the hitch coupler, and then see if with the angle iron free from the hitch coupler if I can just break the remaining welds loose with a wedge and sledge as Mark suggested. Thanks guys, I will report back how it goes.
 
AFA Cutoff wheels, 3m Cubitron III is best hands down. The best grinding wheels also, Cubitron 3 3m,
 
3/64" = 0.046875"
Cubitron II 4.5" diam. are 0.125" = 1/8" (Couldn't find Cubitron III on the 3M website...)

At 3/64", the H.F. are thinner. So if I protective gear up, discard them immediately if I drop the grinder, I will probably continue to use them unless I can find an equally thin wheel. Here's my 3M grinding helmet:

I am wondering if there is a leather jacket with good front neck protection?

Most leather welding jackets should go high enough that the shield and jacket will over lap

I've used a variety of reciprocating saw blades and have had good luck with the Milwaukee and Dewalt blades, haven't had the chance to try any Lenox blades yet. My Sawzall used to cut ALL of my metal stock before I got my power hacksaw.
 
For sawzall blades I have used Lenox for many years they are are not cheap but cut straight and last the longest as long as you let them cut and don't lean on them to hard
For cut off wheels had best luck with Norton wheels they last a good while thought not cheap and may not be available locally http://www.grainger.com/product/NOR.../rp/s/is/image/Grainger/33N521_AS01?$smthumb$
they work well and not that thick
