packing a pris

Hey guys,
When I started with snus, I would pick up a pinch of snus (as if it were dip), and then form it into a little pyramid-shaped thing. Lately, I push my thumb and forefinger down into the corner of the can, packing it down before pulling out the pinch. From there, I pack it more and form it into a pris. Doing this, I've found I can get much more tightly packed prilla that resist breaking up and turning into mouth mud. (Once they break up, I have to re-pack with my tongue - old dip habit - and that NEVER helps the mud situation). I'm not sure when I started doing this - though it probably came from getting the last pris out of a tin when the snus is drier.
Anyhow, from what I understand, the Icetool/Prismaster basically does the same thing, but it doesn't make sense to me to buy a tool that does something I can do myself. Plus, since I use the loose at home, I'm not too concerned with dirtying my fingers - I can just wash them off. Do any of you (those of you who don't use the snustools) use any similar sorts of snus-packing strategies? I am interested to hear about different techniques. Thanks.

Cheers,
