There is an exchange of airflow for lift with the restriction of the holes, this is why slot
glides generally don't dry as well as holes.
Now, that said, yes a bigger blower does allow some room for "fudging" but be careful for what you ask for, as everytime you remove a little more teflon stock the wand becomes that much harder to move, we sell holes to porty users for drying, we sell holes to vortexes so they can move the wand.
Also I will touch on my comment above, as it must ahve slipped by.
RADIUS
there is only so much of a round glide that actually touches the carpet, if you allow margin for the full extended cleaning stroke, as well as the fully contracted stroke, you can only go so big with your holes, and two rows staggered would only be that much more difficult, been there, the hole size has to be reduced to achieve this, and now you are back to square one.
If you feel like it, drill out some existing 11/64th holes to 12/64 (3/16") and try for yourself with your 45 blower, after all the 3/16 is jsut a lil' bit bigger right? :wink:
