I wouldn't say the treble gets better, but midrange will become more open and less muddled. Bass will indeed become tighter by the same logic.
Care to snap a photo and show what your progress is on the pads at the moment? This way I can give more succinct / accurate suggestions.
Here's what it looks like now (some holes look horrible but it's mainly because I was twisting the pads with one hand while taking a picture with the other hand; the holes are quite large and round actually). i checked and the holes are clearly not covered by the flaps and ring, which explains why they do something.
I am not sure it needs more holes though, the balance I get from these pads is pretty close to what I was looking for. Mids are close to perfect. If I ever want more treble, I can just put the velours back in, or change the nylon screen. To adjust the amount of bass (not the thumpiness or kick, that's always there, which is good) I just adjust the how the pads are oriented compared to my head. The more space I leave "behind" my ears (or anywhere around the pad for that matter, but inclined in that direction I get more comfort and slightly more centered staging), the more bass I get and the boomier it gets; the less space I leave between my head and the pads, the less bass I get and the tighter it gets. for now, I choose to have the pads oriented just a tad towards the front of my head, which leaves an ever-so-slight space behind the ears and adds weight to the bass while still clean (like a 1-2mm of bass reflex, kinda like the vents in this thread), it's a trade-off basically.
