Mikey,
Go with the twins. I had the same problem as most with having to struggle getting mine into 4wd and out. I even broke an aftermarket J shifter or two where it attaches into the swivel. Once I installed the twins from JB Fab...I haven't had a problem since. They shift individiully so you can go 2H, 2L, 4H, 4L . You can do just front wheel drive high and front wheel drive low and also rear wheel Low and high seperately. also..for example If you are on the trail moving slowly in 2L rear wheel drive..with hubs locked in..you can shift your front lever into and out of front wheel Low on the fly. No more stopping and trying to get that J into low to spin those front wheels.
Works great and its and easy install too. JB fab gives you the twin stick shifter, the twin boot, and plate cover in a package if you ask. Any questions..let me know.
