I have the Apache's with non-RWRP middle and vintage stagger and the Irish Tours with RWRP middle. The sound without is more subtle, and seems to be the 'vintage' tone, whereas the RWRP is more pronounced, and seems to have more scoop.
I am thinking of a set of MM and will get them with the standard and vintage stagger.
There are 2 vintage staggers (just to add to the mix!), the 54 and the vintage. My apaches are the 54 stagger, this has the G magnet lower and A higher than the vintage , but still has E&B lowest, then E & G then A and D highest.
The vintage stagger makes the top E & B lowest, then the bottom E & A, with the D & G tallest.
I have flat in my Trilogy, and Slowhand and IT when using in a H/S/H or H/S/S set.
