TQFP soldering (follow-up)

I tried my hand at soldering a 68 pin TQFP using the "push the blob
down" method described on a YouTube video. It worked pretty well,
but for one side of the QFP, where there were several solder bridges.
The bridges were easy to clean up using a bit of solder wick. About
the only thing I'd do differently is to tack down two corners rather
than one--it's easy with just one corner tacked to displace the
package slightly with just the pressure of the soldering tip.
I didn't try the "flood and suck" method.
I used the largest chisel tip on my old Weller TC201 iron, a PTC6--a
blunt tip suited to soldering #14 wire, but it holds a lot a solder.
Thanks all for the suggestions,
