Currently I own a 6" Pro-Mark X Pad with a snare cartridge, and a 12" double-sided HQ Real Feel. I've also owned the 12" double-sided Vic-Firth pad.
Out of those three, I like the HQ the most because there is a significant difference between the soft side and the hard side, whereas the two sides on the Vic Firth pad don't have as much of a difference.
That's interesting about the reel feel, which side do you play on mostly? I think the idea is for there to be little to know difference seeing as drum pads are supposed to mock an actual drum.
I prefer the slim pad, and I have owned a xymox, a reel feel, still have my double sided
Vic Firth which i use when i need to be a bit quieter than a slim pad will allow, and those ridiculous drum pads you get with percussion kits that have rims on them.
