Replying to Dynastar px12 jib trouble vs dynastar px12 jib ti big trouble

Im 5'10 150lbs my current bindings are solomon z12 ti's they are set at 8 and i rarely popped out on them i didnt pop out when i should have only once.

I was just wondering how much lighter the ti's would be. and how durrable both bindings are because the ti's are about 30 dollars more and dont look as cool as the troubles.
these will be going on 08 atomic urban punx.
anyone who has either of these info would be great.
also does anyone have 2008 rossi scratch 140 ti's because i was thinking of putting these on 09 bacons.
+karma for good info. thanks.
