I personally don´t understand why everyone here is happy with G25/G27 force feedback response in GT5. The support of smooth ff is nowhere near to DFGT. I own G25 and G27 and DFGT. The fact is that DFGT is a FF winner regarding Logitech in GT5 support. G25 and G27 FF is a bit rubbish in GT5.
Yes, I can undertand the G25/G27 H-pattern and heel & toe combo, but the complete rubbish ff response is uselless in GT5, so at this time I use DFGT and yes, I am a bit dissapointed that I cannot use heel & toe which is second nature for me. But: mine T500 RS will be with me within next week and I am sure, that the strongest part of this wheel goes from ff effects, total control because of smooth and predictable ff and overall GT5 physics / fast response. If their H-pattern shifter will be out in the near future, it will be the best wheel on the market. Moreover: PC support will follow shortly. If you cannot buy a premium product, just stay with affordable products range, but please: take it easy...
BTW: Darin knows what he is talking about and I feel that his Frex and ECCI ff comparison is a very good indication what T500 RS has to offer.
