Small Base Circle Cam

Can someone educate me of the mechanics of small base circle cams?
What I keep hearing is that they should be avoided like the plague.
Something about harmonics and deflection?
If they are so bad why do they make them?
Since they do what are they intended for?

I have a 351w that I'm going to stroke, 393 and am considering using a small base circle cam to convert to hyd rollers of the stock ford type w/spider.
This is a street motor that won't see past 6K rpm not a high rpm screamer that from what I hear so far is where small base circle cams seem to have a problem with flexing.

Will it work well and be durable?

Thanks.

Morgan
