OB4s? I agree- Wileys are a very well-crafted 1970s design. WIleys are super high quality and their wrap options allow pretty good customization, but it's still an old design. What percentage of jumpers use anything else, though- 10%? Less? In my jumping days, I used Connelly HPs, then HO Animals, but I wasn't any good and I was an oddball using those. D3s seem like they'd be a pretty good option.
