Hi. Happy to help. You're in luck... I actually have a pair of Brainwavz Oval Angled Sheep Skin Pads. On my stock B8, they noticeably accentuate the mid- and upper-bass. The sound is a bloated and unnatural with orchestral/instrumental music, but with pop music genres, that bit of extra heft is welcome. Since the B8 is a bright headphone, the treble quantity is plenty strong, but the sound is very 'closed' its presentation, without any sense of 'space'.
The Brainwavz Oval Micro Suede Pads yield more detail, treble, and comfort (breathe-ability and softness) ... and less - but tighter - bass. A very lean, dry presentation.
Compared to the Micro Suedes, the super soft dark grey velour misodiko pads (with perforated fake leather on the inside) have slightly less treble and offer a 'lusher' sound: more bass, sound-stage, and better center-imaging.
Since you value bass, I recommend the black velour misodiko pads, which are a fuzzy suede material. The pair I bought from Amazon also have perforated fake leather on their inside, but the photos shown are all suede. Either way will be fine, as bass-boosting, treble-reducing, and comfort are their strengths. Both of the misodiko pads are selectable as Amazon item B07QV33SJG.
And yes, angled pads offer a large sound stage and more-stable fit than flat pads. But being thicker causes increased around-the-ear pressure. Also, angled pads bring your ears away from the driver, which decreases mid-frequency response.
Just so you know, I was getting my sound impressions while using the portable FiiO Q1 mkII, which is quite affordable and a pleasure to use. What's your current DAC/amp, if I may ask?
