Stock Whips, there is currently, in my opinion, nobody even coming close to Peter Thorndike, though he'll have to watch his tail if as rumoured Chris Barr makes a return, haha, either are the closest you'll get to the best of the best! That one was quite easy.
Good old Steve Huntress from NorEast whips in my book is leaps and bounds ahead of any other synthetic maker in the world, not only in quality of work but years of experience, for some strange reason he liked my synthetic work before I retired from it, over the years we have become email/skype buddies, but he is the guy I always aspired to equal, the very best in synthetic....that was another easy one.
Skip over at HandMadeWhips, my opinion again though I have seen work by all the American makers, he is by far the best thing coming out of America and I do mean by far, he really is a good all rounder, speciality I guess would be the **Woody BullWhip** but he makes a more that good snake and signal too, if you don't want to wait for me this would be your go to guy.
A few hides in my workshop waiting to be plaited just thought it might be of interest, so those are my opinions, I don't mean to offend anyone, you know what they say about opinions, "Opinions are like ar**h*les, every ones got one and most of them stink"
Do remember if you're reading this in the UK or Europe, the price you see on these guys sites are all subject to Import Duty, VAT, and customs clearance charges as well as postage which from America is good but very expensive..
