I had an interesting event happen over the past weekend that ties in with your question.
I was assisting an instructor with a rescue class over the weekend, and for those who have done it know it can be a fairly strenuous course. we had an student that was diving with what looked like a 20year old Sherwood brute, if anything a these are workhorse regulator, but in my experience not the best breathing reg. he had trouble catching his breath and he was over-breathing his reg. when we were on shore I let him borrow my spare regulator (AL Legend LX Supreme) to use for the next scenario. he immediately noticed the difference and realized the benefits of a high performance regulator.
This was the first high performance regulator he had ever used, he had been using this Sherwood for almost as long as he has been diving he did not know what he was missing.
Now the Titan LX is a great regulator, value and performance wise it's hard to beat, soon it will be available with two High pressure ports and when this happens there will be no real reason to buy the legend, as this was the main reason I got mine. the performance and reliability of diaphragm regulators are hard to beat and opting for the sealed version (Supreme) will allow you to dive in just about any condition.
the Titan LX is a great High performance regualtor, you would be hard pressed to go wrong with it.
