I guess it all depends on what their intended use is Maurizio.
RS-29's on track simply fell apart on me after 2 track days (around 5 hours use), and less than 2k miles in total. I also know MattM had an identical experience on this compound. 24 hours my eye. I've had a partial refund from Pagid for my troubles.
On the road though, they don't squeal. At all in my experience! As Nigel says, they aren't brilliant from cold, but will be more than sufficient for road use when up to temperature. So they may be the perfect pad for you.
RS29's will not see my car again. Carbotechs, a mythical race compound from Ferrodo and from what I've heard Carbonne Lorraine simply blow them away for stopping power. I remember Begbie giving me a demo of the XP8's before I ever used the brand, and, in Marcos words, I needed a new spine
Admittedly that was in a different caliper setup, but I can sure vouch for them in the standard brembo 4 pots.
But, the carbotechs squeal like hell. Not that you hear it when braking hard on track. But for this, they're probably not the pad for mainly road use!
