You can ask anyone I drive with regularly. I have no problem whatsoever anticipating and catching slides. You might even say that's my style. Sliding.
A few years ago I was able to test several large and small sims both with and without FF by way of running into large facilities with both broken and working force cockpits and wheels. Also tried FF with GP3 and GPL. I'm positive I get a better read from the car *without* FF. For me, it's simply too loud and slow. It's masks the minute details modern computers are able to communicate with sound and video.
That being said, I bought my TSW Sport in November of 1998. (Hmmm... that's and interesting time to buy a high priced wheel, eh?) Since then I have replace the pots maybe six times. They get them out in days, every time. There was a crack in one of the levers that hook up the pedals to the pots. TSW sent an entire replacement pack free as they decided to use a different material. No problems since, except that I have an analog game cable coming from it. Not TSWs fault that Windows XP doesn't recongnize analog game ports correctly, but as soon as I send my wheel in, they will rebuild it to modern spec for the price of parts. Pretty cool if you ask me.
This is the absolute truth: My wheel feels and opperates EXACTLY as it did in November of 1998. Consistency is the pay off. I never, ever think about my wheel. It's just a part of me. Matter of fact, I am falling apart faster than the wheel. (Oy! My aching knee.)
So, for something a little less than the ECCI, like, about two 3rds the price, TSW is a very good choice. BTW, the Sport is a very basic package. No frills. You can frill until you're blue in the face if you care to spend the dough.
The ECCI pedals are looking very, very interesting.
