help with sleek audio sa6/sa1 tips pleeeeease

[jasonb]

does anybody have the sa6, sa1, or use these tips on any other IEM's?
 
if so i would just like to know the diameter of the bore, so i can see if these will work on a GR01. 
 
also are they the same diameter on both ends, or are they bigger or smaller at the nozzle end.

nvm, found the answer. looks like they are only 2.5mm. i'm assuming if i put these on the GR01 it would alter the sound. from my experience with the CKM500, wider bore tips brought out the mids and highs, so if i put a smaller bore on the GR01 it would probably hide some mids and highs. i really like the sound as is, but just want tips that isolate well and are real comfy so i can wear them for long periods of time. looks like maybe i can try the Meelec M6 bi-flange tips or maybe the UE bi-flange tips. does anybody know how soft the M6 or UE replacement tips from audiozone on ebay are?
