i dont ride so hard to crack it, i think! )) if you mean those few times the frame was cracked, take into account all curcumstancies, especially gaps, landing ground, a race status, etc. So I don't believe thats a risk for me to get my frame broken..
Just don't let air companies to pack your bike when you travel. I've seen a newly bought SS with a dent after loading in an airport..

 Nice bike thinking about getting one have heard mixed reports about cracking,how do you find it
