Mask Advise Needed

First time CPAP user here. I started my CPAP about a month ago. My sleep study showed an AMI of 55. During the study, they had a pillow mask so I decided to start there. I end up getting a Transend Micro 510, because I do travel some and I was going to be out of pocket no matter what I got because of the high deductible on my insurance. I got a Nova Micro Nasal Pillow CPAP Mask.

Here is what I am seeing. My AHI is averaging around 5. I have two issues. One, my nose is a little tender in the morning even after a month. Also, I'm seeing a mask leak around 20 LPM - I've only had two nights where it was 15 or less. I've tried adjusting things but can't seem to make it better - although last night was the single best night I've had 4 AHI and 10 LPM.

My order included two month to return and try a different mask so I need to make a decision within a couple weeks. Should I stay with what I have or look at something different? If I'm changing what would you recommend?
