Of all the wilds I've had, none of them had Sp involved. The few times i have induced SP, they got me too excited to do anything, and i ended up waking myself.But, If you're still 100% set on going through SP to do a WILD, then listen. SP is a natural process, if it happens, it happens. If it doesn't, then try a different attempt. After almost 3 1/2 years of Attempting LD's, I've only ever induced SP around 3 times (5 max). Just let it happen, and it eventually will. Don't make it happen, let it happen.

Then again, some people say SP is the best way to go...
