I'm barely pulling 1300 watts at 60amps. Any suggestions for the next step? A bigger prop like a 21x12?
At that altitude a higher KV would probably be very good. That would give you more room to prop up. For us at lower altitudes a higher kv (400-450) lets us start to run an 18-19" prop, which would let you prop up to 20-21 to get the same power.

So, at my altitude (7500ft), which Motrofly would be the most ideal?

Don't rightly know... I've just seen others that post on here have good success with being able to prop up. There area few, if you go back through this thread you'll find some that live in Denver and other areas up there. If it were me I'd probably try a 4325-450 and spin a 19x10 prop and see that that does for you. I would shoot for watts in the 2000-2300 range.
That is just a guess.
You would probably be best to email Subsonicplanes.com and get their recommendation... undoubtedly they would know more than me. Or you could also try the Hacker a60-5xs, it's a higher kv too and should let you run a 19-20" prop. Would be a direct replacement to your a60-6xs.

pretty sure Joe Smith is running a 21x10 on the A606XS. iirc, he was even considering a 22" prop. just saying you might have some room to prop up before selling your motor.

I keep nicking my wood props on my very short, uneven, and paved runway. What stronger prop options could I run on a hacker a50-12l on 6s...? I need something durable that wont bust at the slightest contact...

hmmm, I'd start with working on the landings, a nice 3 point! For me sometimes a 1 point then drop the other 2.

My 71" slick arrived today. As well as my equipment. My setup is as follows:

Tacon Bigfoot 110 295kv
JXF 19x9 prop
AeroModel 3" CF spinner
Turnigy 120A-HV-OPTO Esc
2 Zippy 4s 4000mah 40C packs in series
Turnigy 15a UBEC
Turnigy 620DMG+HS High Torque Digital Servos (MG) 10.6kg / .13sec / 52g
Spektrum AR8000 receiver

Not sure what size receiver pack to run on this setup though.
Also these wheels seem very hard, what is everyone running? Suggestions on my setup?

You don't need another motor, just a different prop. You are at a higher altitude where the air is thinner, you need a prop with more bite...

They guy I bought my slick from had these wheels on it. They are nice and squishy.

A60-5XS is 420KV, according to Mike at Aero-Model, this motor is designed for 16X10 to 17X10 props (at nominal sea level) on 6S. However, he told me I could run an 18X8 Xoar (I am at sea level). I have one of these in my new 70" Velox, and should have some numbers on it in just a little while. At higher altitudes you would of course be able to use a larger prop.
