USLM 4.2 question

[RTBoss]

Question:
Should / Could I use USLM 4.2 in combination with UMS v2?

Thanks in advance,

Seeing as you don't have an answer yet - I'll give it to ya straight.  

No.

Shannon calibrates these programs very carefully.  Throwing USLM 4.2 into the mix will throw everything off, and you won't see much of anything happen.

Don't do that.
