Pads are a real fun subject! I am currently using reversed 414s on my MS-1 but bowls on my MS2i!
.....current SR-125 come standard with bowls.
For "my" ear size in "my" system, the 414s are more comfortable on my MS-1s than the bowls are, but the bowls sound better if I use an amp, which I never do with the MS-1s so I may as well be comfortable! On the MS2i, which "DO" sound a lot better amped and with the bowls to "my" ears, I end up leaving the bowls on even though the reversed 414s are just a tiny bit more comfortable, but the increase in sound quality makes up for the diference in comfort!
Whew!
I find that with "my" ears the "comfies" and standard 414s slide around a lot, while the reversed 414s allow my smaller ears to kinda snuggle right on inside and be ultra stable.
Now if my ears were bigger, or if were listening to SR-80s or RS-2 or SR-325i......or SR-125..... I may have a completely different story to tell!
