both the 07 and 06 had the breakage 'issues'. you can tell by looking at the seat tube/top tube junction. on the old style frame the top tube was the same od as it was halfway down the tube. if you ran your seatpost too high, you could crack it there. the next generation paragon frames had the top tube ovalized there. i believe my 07 rig is still going strong after i put quite a few miles on it and jumped it off of everything i could find. if you use a long enough seat post, you should be fine.
edit: to clarify that, i sold my rig, so i dunno if it's still in regular use.
