Some of the frames available today are paper thin at the oversized carbon BB shell... Thats the one place where lots of manufacturers have saved a lot of weight by using a multi part form for modling that lets them do a far more detailed job (meaning less material laid up in a more controled fashion that gives all of the stiffness but thinner walls).
There are several frames now that I wouldn't run without a catcher...
I guess you could always ask your mechanic to take full responsibility for a dropped chain and any damage and then call any shop that won't take full responsibility "bad", but a chain catcher weighs very little and the weight sits in almost the perfect spot to have the least felt impact...

I would say save your money and find a better tech if your dropping your chain. The front derailleur is the chain catcher and adding an aftermarket piece is not going to the root of the problem.
there are plenty of instances where the quality of the mechanic is not at fault. sometimes it's environmental factors, a swerve, a shift in the rear simultaneous w the front shift, a bump, an anomaly. sometimes it's a combination of parts-fsa crank, kmc chain, shimano everything else, chainstays 1cm shorter than specified by shimano. sometimes the frame places the derailleur farther forward or behind the crank than optimal. sometimes the front derailleur was designed in chicago. manufacturer tolerances stack up.
i like the new red chain catcher. you can get it separately, without getting the front derailleur, and put it on any braze fd.
with frames dropping in weight and pros having to fill up with lead to be legal, more and more frame companies will be integrating them into the frames, like the trek damone. at the same time, having the chainrings spaced further apart a-la current shimano has helped a lot...

So you are saying you dropped your chain in the the provincial championship road race? And you couldn't shift the chain back on - did it get jammed in the bottom bracket shell region?

I do not have a chain catcher on my Di2 bike. Have never dropped a chain on the Di2 bike. I do have chain catchers on every other bike I own. Probably need to get around to putting one on the Di2 bike.
