looks good , I like the bottle fill plug and it seems a generic bottle with a 1mm id tube would probably work if you needed to. I do like the rubbery obsidian black panels on the one of my v2's and had no luck finding the panels for my other one.
There's not really enough to raise my eyebrows over the V2... For that matter, I still quite enjoy the Pulse X as well, and have a few stashed-away that I picked up back when closed-out, along with the fantastic (IMO) black and brick-red G10 panels..
I also like the V2's bottle system, and while I've read reports of leaking through the bottom cap, I've had no issues with both of mine to date.
Well used and enjoyed Pulse V2 and 'X' fam pic... Both excellent squonkers for the $$ IMO, and still quite relevant in my rotation (EDIT: I was going to include one of my OG Pulse mechs, but didn't feel like digging around for one):
