Re: LTA 50 suspension
this isn't a fix for the suspension, but may help with the bobble-headedness...
Our Daughter (5 1/2yo, 43lbs) had a problem with the weight of the helmet thrashing her around and making her neck get tired. We saw some of the people on the forums reccomending a racing neck collar... one design of these is nothing more than a football pad, flat neck roll. We got one of these at a local sporting goods shop for $10... it attaches to her chest protector. She tried it out this weekend, and I could tell her head was much more stable, and she commented that her neck wasn't so tired at the end of the day.
