I just didn't really care for the way they felt. Without the weighted tails, they moved around a bit, but I never had trouble with them getting in my way.
Yeah, the ones with the rawhide lacing are relatively lightweight reins and I can imagine that going from them to the heavier reins would be a big difference.
Another thing that might cause you to not be sure how you like those second ones is the difference in length. A person wouldn't think that 6 inches could make that much difference in feel but it does.
The ones I get are about in the middle between those two. They are heavier/sturdier than the rawhide accented pair, but not quite as thick as the ones from Jeffers.
These are what I buy...all I've bought for years. Other than a couple that have been broken by greenies, they're still almost like new only better because they are broke in now LOL. Shop Waterloop Split Rein 3/4in x 8ft
