@op - YES the games are very beatable
This whole thread reminds me when Rush poker first came out and everyone was talking about "rush strategy". For the first few months there was no HUD and everyone thought we need to reinvent our strategy. Turns out the same good poker fundamentals that work on regular tables work on fast poker tables.
If you are really serious you can study player pool and make a few tweaks to add a little extra EV.
Here is some tough love - if you can't beat 25NL zone you aren't that good at poker. Hit the books guys and work on your game
