I have read most of the lambic posts on this board but would appreciate any other suggestions for a first timer? Thanks.

I have had good results keeping things simple. 60% Pils 40% wheat. primary with a neutral yeast like WY1056, and then pitching WY Lambic blend when primary slows. This is a fairly common and well known method that produces a nice lambic within a year.

Other posters here do "supplement" their lambics with various dregs, bretts, and other bugs and get great results. Still, for a good first attempt keeping things simple is a smart place to start. Good luck.
