Multiple data sets with ListPlot and different PointSizes - Mesh

Hi,
I would like to plot a few data sets with different PointSizes using
ListPlot.
My format: {{x1Pos,y1Pos,dot1Size}, {x2Pos,y2Pos,dot2Size},...}
The initial state:
data1 = {{1, 1, 3}, {5, 5, 6}, {6, 8, 10}}
data2 = {{1, 2, 10}, {2, 3, 5}, {6, 10, 16}}
data3 = ...

Any solution would be appreciated.

I found a handy example in the help: ListPlot / Mesh / Use explicit
styles at specific points

ListPlot[Table[{x, Sin[x]}, {x, 0, 2 Pi, 2 Pi/20}], Mesh -> {Table[{x,
Directive[Hue[x/(2 Pi)], PointSize[Medium]]}, {x,0., 2 Pi, 2 Pi/8}]},
Joined -> True]

My go:
For a more readable code:
data1Plot = Table[{data1[[i, 1]], data1[[i, 2]]}, {i, 1,
Length[data1]}]
data2Plot = Table[{data2[[i, 1]], data2[[i, 2]]}, {i, 1,
Length[data2]}]

dot1 = Table[{data1[[i, 1]], Directive[PointSize[data1[[i,
3]]*0.002]]}, {i, 1, Length[data1]}]
dot2 = Table[{data2[[i, 1]], Directive[PointSize[data2[[i,
3]]*0.002]]}, {i, 1, Length[data2]}]

Everything is fine with one data set:
ListPlot[data1Plot, AxesOrigin -> {0, 0}, Joined -> True, Mesh ->
{dot1}]

But with 2 sets of data, Mesh just take the first argument of its list
and mesh the two data sets the same:
ListPlot[{data1Plot, data2Plot}, AxesOrigin -> {0, 0}, Joined -> True,
Mesh -> {dot1, dot2}]

I hope it's clear enough.
Thank you in advance!
