If you think the 93.5 is too long, why not try something shorter? How about taking the current blade off, loosening that tensioner as far as it will go and putting some string around both wheels to get an idea of the shortest blade you can shove on there.
You can get blades custom made to length, but there are some standard sizes just below 93.5 also - 92, 92.5 etc. They're just a smidgen harder to find than the others. Hartville sells 92.5, that's an inch less than you've got now. If the string shows that would be too tight to start, then you can try ordering a custom 93.
Insert witty signature line here.
