Here are my responses: For my level of skating are the freestyles/competitors a good boot for me and if you've had either of these skates before did you like them?
I wore Competitors for about 2-3 years and didn't like them at all. The stock blade wasn't half as good as my Gold Seals - the Ultimas were slow on the ice with an odd rocker placement. I ended up changing skates before the boots broke down because I just didn't like them at all.
I have a skater at your level who was placed in Jackson Premiere's, which work well for a tall/heavy skater. The fitter says they're better-quality than the Competitors.If its possible to answer, about what stiffness rating should my boots be?
I don't know if the stiffness ratings are fully standardized, but you are a USFSA Freeskate 4-5 level skater, so the fitter can make a better recommendation than an internet chart.
Kinzie's Closet has such a chart, but some of our members have contested the accuracy. I will say that my fitter does overboot heavy and tall skaters because they break down "chart perfect" boots too quickly. Sometimes, it's worth going up a level in stiffness to make the boots last longer. https://www.kinziescloset.com/skate-comparison-guide.htmlAlso, how long and how hard will it be to break them in if I end up going with them?
That depends on you - your current boots probably felt fine within 2-3 sessions because they don't have much support. They molded to your feet more easily. The stiffer the boot, the longer the break in, assuming they are correct for your level. My Competitors took about 20 hours to mold/break in, with adjustments and exercises. The Harlicks I'm wearing now took about 10 hours of skating to break in properly.
Proper sizing is critical - don't fool around ordering off the internet because, ChristyRN pointed out, you'll be in these skates for a while since your feet won't grow very much. Ask the skating coaches and high-level skaters to recommend a fitter. Ask them to measure your feet, length and width. Be prepared to ORDER and WAIT for the correct sized skates. Don't be tempted to buy something in stock that's not the right size. Sometimes, people will buy a larger size when they really need a wider width. Tripping over the toepick while skating is not fun at all.
A few years ago, I had a skater go from Classiques, which are Jackson's highest-level beginner skates, to Freestyles. The sizing between the introductory skates and the "specialty" skates was radically different, so while you might be wearing a 7 in Artistes, you might need a 6.5 in Competitors. You have to try the skates on to see which size fits well.
Another thing to consider is that you should upgrade to a freestyle blade like a Wilson Coronation Ace or similar if you're doing spins and jumps. The difference between the Artiste stock blade and a CorAce is incredible. Your jumps and spins will improve, once you get used to a blade with a rocker and more prominent toe picks.
