at ditching the opti on a stock/near stock car. The stock ignition system is more than sufficient for 99% of people's needs.

I agree with ss.slp.ls1. the origional stuff is fine, but the rumors to less informed people believe that the OPTI is complete junk. You can go to a Delteq system also if your wanting individual coil packs, but as stated above the Delteq uses the origional OPTI to operate. If the car is basically stock then there is no need to worry about it until it gives you problems and if it does just put a new OPTI in it and it will give you many miles of trouble free service.

was your car originally a 6 speed or did you swap rears? the A4's have 3:23s if they have the performance GU5 axle and 2:73s if they have the standard axle. only the 6 speeds had 3:42s

Hey:
How about just changing the cap and rotor on the opti like you would on any other distributor after 75-100,000 miles. They need maintenance and love too. GOT 120,000 miles out of one opti and 247,000 miles on the other vehicle and its on its 3rd cap and rotor, 1st 2 gm , 3rd now msd (Vented).
My third lt1/4 vehicle has an ltcc/dynaspark and only has 10,000 miles on it since the upgrade/build, I like it, but has way more wires and cost a lot more to do. I have not put the miles on it, as it's my toy and gets driven on nice weekends only, so I can't say if it's a great deal more reliable than the other opti cars or not, but it should be
Imho If you dead set on a coil pack setup go LTCC and Dynaspark gen 3

I have not seen, nor can I give you any experiences on this kit, but you can also look at the LS conv kit made by EFI connection,
http://www.eficonnection.com, but that is by far from cheap if you get all of it from them, (wiring harness) but they have info to help cut some of the cost down by doing the labor on the wiring harness yourself.
Also there was another guy (akafred), I think that was doing something like EFI but was a good deal less expensive but don't know whatever happened to his project/kit
Good luck on which ever way you go, but if you want an LS type coil system
maybe look at a whole motor upgrade, it may cost less in the long run if you don't have the LT motor built or need to buy long tubes anyway.

even though the ltcc and the deltec doesn't elimate the opti it take away the harful voltage from the optical sensor, thus the only use of the opti a more or less just a fancy camshaft sensor.
Personally speaking i have the LTCC setup and i apsolutly love it, eventhough the install was quite detailed and time consuming.
