I think this is where you're going to have to experiment to find out what works for you.
For reference, here's what I went through to get to where I am now. When I started to experiment with profiles, it was because I had gone down half a size in skate, and it exasperated some flaws in my skating, in terms of stability in crossovers and getting up on my toes too much when accelerating. First thing I did was work on my technique to see if I could correct the issues. I tried for 6 months and only had marginal improvements. So, I got a second set of steel, and I went from a stock 10' profile with a 3/8 hollow to 12' profile with a 5/8" hollow and a +1 pitch on the new steel. Noticeable improvement in stability on crossovers, but also noticeable loss in agility, but that wasn't a concern because I had plenty to spare. I liked what I felt, but I wanted to see what a 13' profile would feel like, so I took my old steel and got it profiled to a 13' radius with a 3/4" hollow.
Felt like it was a bit too much with the 13' so I stuck with the 12' profile. Another 6 months goes by. Still having issues with getting up on my toes too much, but stability is on point. I try the 13' profile again, but after getting used to the 12' profile the 13' now feels almost exactly like the 12' profile. So time for another change. I get my 12' steel profiled to a 13' with a neutral pitch instead of the +1 to try and keep me off my toes more. Turns out this is another step in the right direction.. More time goes on. More experimenting with other parts of my skate's set up. Still having issues with getting on my toes, so I do something way out of the box, I tried a negative pitch. Again, a positive step. BUT, this time it there was a big price to pay. The negative pitch made the heel area less stable, so I had stability issues again. I did some mental math and went to the shop asking for a profile larger than 13'. They didn't have templates for anything larger in a single radius. I thought about it some more and looked at my options. I ended up doing something even more out of the box. I went back to the shop and asked for a 13'/26' duo profile (which some goalies use) with a negative pitch and a 13/16 radius. This is what I'm on now except I'm on a 1" hollow now.
This is what works for me. It not only allowed me to correct the issues, it allowed me to advance beyond what I was before. And the loss of agility, I don't even notice it any more. In fact, I'm sure I gained a lot of it back by simply becoming a better skater.
In all honesty, profiling isn't a quick fix. There's no magic bullet that solves things for all people, so don't expect perfect results. It's a journey comprised of a bunch of tiny incremental steps, where you need time to assess if something is working or not. Each time I made a change, it took a while before I could genuinely tell if it was helping or not. and how I wanted to proceed. Eg. A 13' profile was too much at first, and now, it's not enough.
Any ways, hope some of this... whatever it is... helps.
