Mike,
The Lethal Weapon will have everything you need EXCEPT you can't get the pin gaps tight enough!
The way the pin blocks are designed the only way that you can get tight gaps is between the top and 2nd pin, or the bottom and 4th......you can get tight gaps with 3 pins but not with more than 4.
The top and bottom pins are angled to provide tight gaps but the 2nd,3rd and 4th are straight and you can't get them close enough together because of their mounting blocks.
If you shoot only 3 pins,(Top angled ,Bottom angled and 1 middle)no problem, if you shoot 4 you will have one gap that will not match.
For my Sure Loc razor pin attachment it's not a problem because I can lay the frame back on an angle which makes the pin guard circular and brings the gaps down as tight as I need......the Lethal weapon while a quality sight cannot do this.
I shot against a few guys who had the Lethal Weapon and that was their only real gripe. Pin gaps.

Most top Pin class 3D shooters are using Spot-Hogg "Hogg-it"s , Copper John ProIII's , and the like or pin attachments on moveable sight bars etc.......Another newer sight on the market I am hearing very good things about is the Sword Acu-Site. They have a 3rd Axis Micro that looks great and has a built in lighting system.
I also see some guys with Extreme and Viper sights.

What sort of budget do you have on a new sight? I know they can get pricey.
