that is good to hear! She is on the jackons that come with the boot. I am told all jackson have the 8 ft rock, so anything ultima we can't get since coach wants her to get into the 7 rock since her spins are really holding her back.
Jackson's Ultimas are clones of other blades; the Legacy is an Ace clone, there is also a Gold Seal Clone, Pattern 99 clone, etc. Jackson themselves advertise this with a cross-reference chart. Now, they don't show a "match" for the Ultima Lites, however, our blade gurus have identified it to me as the same profile as an Ace. There is no "magic" to a 7 foot rocker for improving spins ... otherwise, everybody would have that same rocker ... also, the change in rocker will definitely affect jump landings, and stroking. We had quite a problem for both kids changing from a Comet to an Ace - it took more than a few weeks - and the spins also had to be re-gained ... there are always tradeoffs, and everybody is different in terms of the rocker, toepick etc that suits them. The biggest improvement for spins came with stronger core strength and increase in those lovely upper leg muscles that are needed to get UP and DOWN - basically off-ice stuff ...Here's a link to the chart:http://www.tournament-sports.com/_uploadfile/catalogues/Blade%20Comparison%20Chart%202008.pdf

I'm really good at geometry, so I'm sure I'll understand the explanation from the various manufacturers' reps, but right now, there's something not clear to me. The only thing I can think of is that they expand the rocker profile to the larger rocker radius proportionately.
