I don't think the holder length was ever my problem...I discovered that a sharpener decided to banana the toe on one of my skates and thats what was causing me problems.... My skates are at the shop now getting lifts put in and new steel so we'll see how it goes when I skate sat.
I made the switch and my biggest problem is getting used to the shorter blade, there's time where I get my weight to far forward or backward and it causes me to stumble a bit where if i had the longer runner i would be okay
