i have that combo in my strat. Its pretty damn good.
Dont know if this interests you much but....
make sure you know whether your middle pickup is the regular ssl-1 or the RWRP ssl-1. If you buy an RWRP version then you will get the hum cancelling effect in positions 2 and 4 of your 5 way selector (which is pretty standard for strats since the 60s). If you just get a regular ssl-1 then you will lose the hum cancelling effect in those positions. I actually prefer non-cancelling because i feel the sound in positions 2 and 4 are a truer "blend" of the sound of two pickups, whereas when they are hum cancelling the sound seems to thin out a little. It all comes down to what you prefer. Its just a matter of making a decision about which way you want to go when you install the new pickups.
