Many people prefer the look of seimitsu buttons due to the fact that you can put art under the actual button, however if you prefer the look of seimitsu, but like the feel of sanwa's you could replace the spring (just like cherries) and have the look and feel (surface) but the force of a sanwa (and you can light it up ....)
This works pretty well with 'small-switch' Seimitsus since you can just swap in the SW-68 Sanwa switches (snap out, snap in, no tools), but most of the stuff they're making now uses the large switches (2nd from right).

My favorite swap is large-switch Seimitsu for the Sanwa G1 switch from the Sanwa RG buttons. It raises up the plunger a little bit, but the feel is pretty cool. You can barely hear it in play, but this is a clicky switch. They're about 5 bucks a pop though for the switch alone.

@Robokrikit-
~ <3, Sadly I don't really play thhaaaat much anymore, however... half of the videos are all misplaced on youtube due to random spelling as Victheslik, Victheslick, Vic the slick , and son and so forth.... however if you are bored and wanna see some third strike (SCR-SoCal Regionals) I did peace out Sako in losers (read: scrubbed out) xD~ however for finals the next day Fathers birthday (family first) so I was obligated to let others players get ahead ~
Haha, nice job vs Sako. I missed SCR but saw most of NCR the other weekend.
I played the most during WW, CE, HF days out in VA, but I still love SF and get in some playtime when I can. Buktooth's crib is nearby and I've been over there a couple times, and I've been teaching my younger brothers (<= 18yo) to play.
