Sure glad I read this.
Paul, don't modify anything, if you are not happy with the "look" of a Hybrid, it's GreenGlides policy to Exchange your Glide for a Slot or Hole glide of your choice, Free of charge.
So send me an email and I will ensure you receive the glide you want, our guarantee is unlimited so it matters not that you modified yours, I guarantee you will be happy with one of the other designs as this is probably what you are after with your mods....only you won't have to compromise structural integrity in the pursuit of perfection.
Mark Although the Glides "generally fit like a glove, there is some variance in the welding of the stainless steel, so a lil' dab of GOOP on the corners will ensure you are good to go, I will send you some today, just email me an address. Now that said, to be perfectly honest a small "trickle" of airflow on each corner of the wand will not effect extraction with a TM, now I said trickle not a LEAK!
So....how much is OK and how much demands a bit of sealer?
Judge by your extraction, as long as you are recovering well you leak is not a leak. BUT if you are leaving wetter carpets, you now know what to do, so get er' done!
