I have two pairs of bio driving lines. One is more flexible than the other. The “softer” one is my FAVE! I sold my leather lines in two seconds after being convinced i would “like” leather more… But i am a pleasure driver. I just like the feel of the softer bio ones, personal preference.
I have two bio harnesses, one is rather plain, however NICE quality and very very close in feel to leather, it’s a “softer” bio for lack of better words…
My other one for my mini is stiffer. But it has a shiny patent on top and looks much fancier than the other. I do use it for trail driving, i dont show. And i sure wish it was made of the softer bio of the cob harness. It was cheaper… Though for my mini, i will say it is very light, and maybe the softer/heavier bio would be too heavy… I dont know.
The Carriage House is my cob harness and it is SUPER, you can also order all replacement parts from them if needed. It’s just as heavy as a quality cob leather harness. You wont save yourself any weight. BUT, i do hose and just wipe down with a rag. I’ve scrubbed it once since i bought it a year ago with dish soap and a horse brush, i bought it used (4yrs old when i bought it), it still looks like brand new.
I’ve heard some negative about Zilco, but it is popular. I would say you could find good quality amish bio easier and have more access to replacement parts, probably get it more custom depending on who you are ordering from.
My mini harness is just plain cheaper and i cant wait to replace the thing, maybe for christmas! But it cleans up just as good and i havent had any problems with it in the year i’ve had it and put many trail/road miles on it, hills etc… Same as my other bio, i hose it if it’s bad and wipe it, it’s been scrubbed with dish soap once…
That being said, i would love a nice leather harness, but i’m in the south too and it would be white/green like my saddles get. Mind you, my bio will too! But not nearly as quick. The mold likes the softer bio harness, it’s never touched the stiffer mini harness.
I just bought a bio draft halter bridle from a company i cant recall right now, talk about SOFT bio!!! It is getting better, this sucker is so close to being like leather, if i sprayed it with some new leather smell i could fool a lot of people! Those reins are the most awesome reins ever. I want to buy a smaller set for my cob. I prefer those bio reins to leather hands down for riding… I wish i could get a pair with hand stops for my dressage bridle! Good grip, good weight, good feel… Just awesome reins. Otherwise, i ride with all cotton web reins.
I do ride/drive with thin leather gloves. Maybe that makes a difference? But i am really digging the newer soft bio coming out.
