I'll make a vote for the Ripper. I installed it about three weeks ago and love it. I have it set to the rear most setting and use a CDC T-handle. I would have to say it's an excellent shifter.
The steeda tri-ax was my first mod and it was a good one! I'm 6'2" with somewhat short arms/legs so I don't sit all the way back in my chair and I only have to lean forward a bit to put it into 5th
