I got the WB-LS bench. It's bigger than it looks, and requires more space to move around it, adjusting weights, and for the travel of the leg extension, and for the weights to travel on the pulley system. Just guessing, I would suspect their multi-sytem would require a 12 x 12 space.
Cons
1st it's 82" tall instead 86" listed on the specs. I could have assembled it in my 1st room of choice, if I had known. Actually this is a PRO, but just wish I had know before assembling it.
I'm 6'-0" with 35" arm sleeve length. The cable doesn't have enough travel in it for some exercises like lat pull downs.
I needed a LOT more weights than I originally thought. I do leg extensions on a cable system with 80#s. I need 140#s on the powertec. I can bench 40-50 more lbs on the powertec than free weights. The reason is you're not lifting the entire weight, until the weight becomes horizontal near the end of the rep. At the beginning of the travel, you're just pivoting the weight instead.
The weight plate collars should have the hole for the thumbscrew offset more. You can't slide the collar tightly against the plates because the thumbscrew will hit the plates when tightening it.
I spend a lot of time changing plates, and setting up. If I have been doing bench presses, then switch to lat pull downs, I have to unload all the plates on the bench press arm, in order to lift the arm, and pull out the holding pin, to lower the bench press arm out of the way for the lat pull downs.
The foot rest bar for the lat pulls isn't wide enough for me to comfortably place my feet on. EDIT: I assumed this bar was a foot rest, but I guess its a hand rest when laying on your stomach, doing leg curls.
It seems there aren't enough adjustments for incline, decline bench positions, and for the bench press arm pin. The bench press arm feels like it's either too low, or too high, at the beginning the exercise.
When doing flat bench presses, the bar feels like it's pivoting out too much toward my feet, feeling a little unnatural. I have to incline the bench quite a bit to get the feel of a flat bench press.
The end caps on the foam pads constantly fall off during leg extensions, if I brush against them.
Had a couple of places where the paint was chipped off.
PROS
Solid, well built, doesn't require a spotter.
Feels safe to use.
Not as difficult as I thought to assemble it, a lot of it it was pre-assembled.
Probably as good or better than any other home gym for the price.
