I'm running the basic Exedy one, with the matching lightweight flywheel. Feels the same as a stock one in terms of pedal feel and engagement. Drove for a few years at 268kw or whatever it made, no worries.
If you're taking engine out, make sure to do the rear main seal and the kidney plate (well, you would do these if you were dropping the box out anyway). I'd probably do the rocker covers while it's out. Don't touch the turbo unless you have a specific need to, although since you'll be removing the downpipe you may as well do that gasket.
