Yes, safe to flash. But don't wipe or flash ROM's with it just yet. ( If you did, the worst that could happen is the equivalent of a wipe on stock ICS - and Samsung believes that to be safe. Entropy still has his doubts...)
Amazingly, free RAM increases by about 200mb after flashing! Phil thinks it is a placebo. Should be interesting to hear from other users. I have no MTP issues with either version. Try a rear USB port and unplug then replug if you still have problems.
You can safely flash back to patched version later if you like, and Ram gain will still be there!

my ram doesnt bother me , i hover around 650 - 725 when im busy with my phone, no reboots or crashes.
remember not to check just after a reboot which is not really indicative
just MTP is really weird....even now ..... i can see just one sub- folder within main folders, for example i have a folder named 412 and i see just ls7 stuff but i cant see the LSA folder :cyclops: but i can copy into the 412 folder
everything fine with external sd though
if i use usb switcher i can see all the folders and sub folders , some with a dot to start with as you had mentioned. in booted up android i have no problem viewing all files and editing through file managers.
i did clean installation, very clean
im on the latest 3.71, my build version says JZO54K.N7000XXLSA
