Mikron vs Legend vs Legend LX vs MK25+s600 or other recommendations ??

no different than adding an adjustment knob to the xtx40.

Waayyy over the head of the OP

There's no different in breathing, right ?

Any 2nd Stage regulator with short exhaust vents will have some bubbles in front of your mask

What MK21 combination can you find where you are? The MK17/S560 or MK21/S560 are awesome combinations. Try harder to find them

They only have s600 and above for this line.
Would it be different if I pair first balanced with unbalanced second ?

Scubapro second stages: The S600 is an adjustable regulator with a metal air barrel. The S560 is the same regulator with a plastic air barrel. (NOTE: Older S600s also used a plastic air barrel). The S360 is an S560 without the adjustment. These should all breathe the same. The S360 and S560 can be upgraded to the S600. The G260 is the same as the older G250V in a smaller case.

The S620 TI is a new model that I believe uses a titanium air barrel and a smaller case. Supposedly the case and/or exhaust valve reduces the exhalation resistance over other Scubapro models.

What are pros/cons of plastic & metal barrel ? Does metal make it easier to take care of ?

 

[runsongas]

metal helps a bit with dry mouth and also makes it a bit more resistant to freeflow when diving cold water.

a balanced first with unbalanced second works fine, it just may not feel as smooth as a balanced 2nd. also, it generally is harder to tune an unbalanced 2nd to very light cracking pressures because you don't have an adjustment to increase the resistance when needed to stop a freeflow if it occurs.

The Core is the new name for the former Titan model. So essentially the same regulator.

The same as the Titan LX [Supreme]. With some cosmetic differences in balanced second stage.

Core first stage is the same as Titan.

Titan is still offered paired with an unbalanced second stage.
