No I really did mean 3 x str and 3.5 x str ... for 2 x str or 2.5 x str the feat would not be used at all ... ever ... in our campaigns ... and thats usually a good way to find out what's the right interpretation for your campaign.
How many times it is balanced in your campaign to add your strength together really depends upon how much people are power gaming their strength scores. If people are running around with "normal" strength scores of 14-23, then tripling like the text says really isn't going to hurt anything.
However, if people start really power lunging into the rules in order to get strength points, it can become unbalancing quickly. At high level, for instance, if you can get your Fighter's Intelligence up to 21 (even temporarily - which you can), then you can transform your Fighter into a Titan, permanently. You just slap a Polymorph Any Object (which can change his intelligence, so you can actually cast it twice in order to make the Titan transformation permanent). Once he has Titan strength (43), you can start adding additional bonuses (such as levels, wishes, raging, enhancement, and enlargement), and just for fun you can make him a ring of Alter Self which will allow him to stay in his original form and keep the higher physical statistics.
So without too much sweat (and less than 20,000 gp worth of equipment), a 15th level Fighter can have a strength in excess of 50. Now, when people start having a strength bonus of +22, then suddenly tripling it just doesn't sound like all that great of an idea. That and a Spirited Charge will take a Pit Fiend from full health into unconciousness right through its DR in one hit.
So "what's balanced" is going to be determined by what
else your DM allows. If you play to high levels, and allow Polymorph Any Object as written (Transmute Water to Dust and all!), you're going to have problems playing Power Lunge as written (which gives you 3.0x and 3.5x strength damage with a one or two handed weapon).
Now, I personally cannot see the game balance justification for making the bonus to two handed weapons half as big as the bonus to one handed weapons. Two handed weapon fighting is already a kind of sketchy combat style - I'm just not seeing why the fighting style whose whole purpose is doing more dmaage should get
less damage from a feat that also just adds damage.
So if you powerlunge with a long spear you should be doing 2.5 or 3.5 strength damage, depending upon what else you are allowing in your campaign.
