If the parts don't fall out by their own weight there's something
wrong with your desoldering tool.
That transformer I mentioned the other day, which I changed 50+ times,
I did that with the (very modified) chinese Zhongdi station.
It was a 12 pin throughhole part, ground planes on one side of it, but
I did oversize the holes slightly. I always do that on prototypes
where I expect to change parts often, otherwise 50+ soldering cycles
is unrealistic and the board is toast after maybe 10-20 cycles.
I would not want to work without a desoldering station, those spring
loaded eye pokers or desoldering braid do not even compare.
Sometimes when I make prototypes I steal comonents from junk boards
rather than get my ass out of the chair and fetch new ones, that's how
a decent desoldering tool must work, at minimum.

I've used my Radio Shack solder sucker (not the bulb but the spring-loaded cylinder version) with pretty good success but I have lifted a couple of pads along the way. I really, really need to get something like the Hakko. I watched a video this morning where it was used to desolder a component board from another board that had around eight pins soldered with through-holes to the larger board. After the Hakko was finished (in less than a minute total time), the secondary board practically fell out. Impressive.
