I have a few types of pads. I'm pretty sure among them I have the same as you do -- beige woven with a "y" split in the lead built into the pad.
However, I prefer the Santa Medical pads from Amazon -- their adhesive is better and though there is no "y" split, they have the exact same effect.
As for pad size, I think the only relevance there is adhesion. I have various sizes and one way or another, the current gets through the skin and into the muscle. So, in my opinion, find the pad that holds on best but isn't so large it interferes with placement.
Pad size will not have any relevant effect on received current. In theory it could (consider wire gauges and resistance), but the current is so low and the pads are already so broad that anything from a few millimeters to a few inches will not yield any felt difference.
I think the key is -- stick with what sticks!
I haven't even considered consulting my insurance about
this as the units are so cheap. Although I've seen many times TENS units being sold at 10x or more their real price, they can be bought on one's own for just $25-$75. In fact, somewhere I saw a TENS unit charged to insurance for about
$2000. Our unit retails for $35-$45.
One negative with our unit is that it can't be easily adjusted in the dark (except for the current). So, I also bought one that has a lit screen (and IF).
as well as a smaller unit that I can more comfortably wear on my belt when I'm out of the house. See: www.otcwholesale.com/promed-prom503dblk.html
I presume I'll also get a replacement "twin stim" from the retailer, but this way I can use whichever best suits what I'm doing at the time.

Prices are not the best, but this at least should give you a sense of the wide variety that exists.
