Benchcrafted 12 week minimum out Lie Nielsen twin ok alternate?

I have been designing my first workbench after reading both of Christopher Schwarz books and a host of others and after pouring over designs I decided to go with either the split top Benchcrafted Roubo or the standard Roubo, I picked out all the hardware and was ready to head down and pick up some ash in the next couple days and found out that both of the Benchcrafted vises that I wanted to put on there are at least twelve weeks out! I was going to use their Wagon/Tail vise and their Glide leg vise but they are in the process of changing their molds for the hand wheels and are way out. I was pretty bummed as I think their stuff is top notch and I am so eager to start and I have enough time to work on it right now so I was looking at alternates and thought why not just put a Lie Nielsen twin on the tail and go with a large wooden screw for my front leg vise. I feel like I am settling by going this route but don’t want to wait at the same time. What ya think?
