aluminum flywheels: how LONG do they last?

[34T]

thinking about an alum flywheel for my transplant when it goes in but I don't want something that might come apart a year down the road, either. Has ANYone run one (or had long experience with them generally) for several years?
How much abuse? Run it at the track (any track) or high rpm highway driving etc etc?
I want to get some idea of how these compare to a std ole steel one. Might be of use to a lot of people - and yes, I looked; LOTS on clutches but nothing I could find on any LENGTHY useage of an alum flywheel. Maybe they just don't last????....... Can they be resurfaced? Are they just too expensive? What race cars are using them (might be interesting); Maybe something on brand names and customer service/support, too.

AND lets make this for those who have experience, good or bad, NOT just opinions; you know how it goes - an opinion and 25 cents will get you a cup of coffee.....

the wear surface is replaceable, they probably aren't resurfacable however//

I have other vehicles with them and have no problems. Yes, they are worth it. Yes they hold up under hard conditions. The wear surface is replaceable steel face that is bolted on by most standards and are built for safe street and road race/drag race conditions. If you want a car to rev up quick, as the GM 60 degree V6 likes to do, they are very much worth it.

Big problem for Camaro and S10 owners that have the 2.8, 3.1 and 3.4L motors, these were never manufactured- until now! I am having a run manufactured for our shop of which we have a few left. The Front drive motors have had some built previously, so i think they can be found if you look, but the FWD and the RWD flywheels are two different sizes, so never the two shall meet.
Anyways, I like them enough to have a run done and place these in two of my vehicles- My 1982 S10 with a 3.4L SFI Camaro motor and a 3.4L SFI (L32) Camaro powered MG B. My Austin Healey also has one and my brother installed one in his Saturn last year.

FWIW,
