It will probaly take you a few weeks to establish your new comfort zone, and then you might see higher scores as you won't need to make nearly as many large adjustment chasing oil. My experience on syns is that once you find a line, your pretty much set for 5-6 games with very minute adjustments. Strokers tend to find their happy zone 1-2 boards away from their current happy zone, and as long as they wall up the outside, you'll get many of the same breaks. I've often been able to play my exact lines with a simple ball change. If you don't have an arsonal, you might have to make more of a drastic change. I've bowled in 3 different houses with syns this year, and was able to play the exact same line in all three, but one house I used a trifecta, the next a Paradigm, and the thrid, a Desert heat.
My house is doing the same thing this summer, putting the laminate right over top the old lanes and then working with brunswick to put out a similar fluff shot.
