Leak on Inhale only (suggestions on mask)

[Gene321]

    I have been fighting this issue for many months.  The problem is big leaks when I inhale only, exhale is fine, breathold is fine. also pressure builds and builds I assumme to compensate for the leak. the only way to "reset" is pull the mask away until the machine auto turns off then start again.
I generally use a Vitera mask and have replaced it. I use both the medium and large, ( large gets addition leaks ) I recently tried the new Evora, and while that doesnt seem to leak ( some at the corners of the mouth on the medium), I cant breath. the medium nostril size is close but not close enough but the the mouth width is too narrow while the large blocks the nostrils and the mouth is right 
Any fix suggestions or recomendation or a differnt mask? - I am a side sleeper and turn a lot - I like the hose on the vitera as the elbow easily turns when I do ( unlike its predecessor) and I keep it tucked above my shoulder when facing away from the machine.
