What are the pro's/con's of 2x'ing in soft high rake games vs the more conventional 2.5x/3x? If you can, please elaborate on the reasons. Thanks.

From my understanding, the reasons for 3x'ing or larger, such as 4x in live games, are to build bigger pots with a tighter range vs loose opposition, slightly discourage flatting, and pay rake less frequently(but more in rake because of the bigger pots generated).

For 2.5x or lower, the reasons are to play slightly looser ranges while giving opponents the chance to make mistakes by defending too wide or too tight depending on the player type and to pay rake more frequently(but less per pot since the pot will be smaller).
