It will be different but that is a personal decision. With Profiling and pitch adjustments (using the pitch holder as well as profiling) you maybe able to get it to feel similar. I only go with longer holders when there is a balance issue. I wont just do it for the fun of it. I know you can go with more blade on a shorter holder but all my clients that have balance issues that I change the holders for prefer the longer holder shorter profile. Example: Had a player get new skates at school at RMU. they are a grinder type player and need the balance to battle. The old 5.5 skates they had had 254 stock holders. The new skates had a 246 but looked good on the skates. However no matter what they did profile wise they didn't feel right and the player hasn't used them at all in games. They came home for the break switched to the 254 and it was like a light switch and they feel perfectly fine. It is all about making the player perform the best with the best amount of blade for that player!
