Your right chris you do have to change the way your playing for diff sites, specially PS and FT from when I used to play on them. I avoid PS and FT but use PP, WH, BS, UB. And i"m by no means an expert but its interesting to hear that i"m not the only one who shifts play on diff sites as well.
Its crazy how many sites there are out there! Imagine if they all merged and you had one big online WSOP that everyone entered - it would be murdurous!
