I use Drennan, can’t fault them. I did buy a few hundred off eBay - recommended on here - and they went in the bin, they were disintegrating during a match. The cost is pretty irrelevant, they aren’t expensive.
I prefer Gardner 3.2mm but be careful where you buy them as I bought some from the bay once and they weren't a patch on the shop bought ones. Not sure if they were seconds or not, but came in the Gardner tube and packaging
Just taken delivery of a thousand red micro bands on eBay from China, 3.99 including postage from China , and they are brilliant , super micro size for red 4mm pellets. I’ve used their normal colour ones all summer and can’t fault them.
You miss a lot of fish, all species feed off the bottom at times. Some commercials are so silty the fish don’t want to be down in it, it’s not pleasant stuff, so they are easier to catch on the drop or off bottom. On many silty venues, the skimmers sit off bottom and follow a bait down, often the best fish come just as the float is settling. By not fishing a rig that drops slowly through the water, these weight builders can be missed.
You can fish on the drop and on the deck, just have an extra rig set up with just 3 or 4 No11’s spread out, so you get the slow drop (lay it in rather than lower it) it’s worth a go, some days you will catch fish on this type of rig when you struggle for bites on a standard bulk and droppers. Plumb it up at depth and you’ll cover all depths by laying it in.
If using pellets, I prefer to use a band slightly smaller than the pellet i am using. If i use a micro band with a big pellet, it tends to slice the pellet in half as the pellet absorbs water and expands, and this means you need to change the bait more often.
