Someone help I cant figure out what the diffrence is between the Slg and the matrix rail can some one help

SLG is a sear-tripped blowforward. The PMR is a fully electropneumatic unbalanced spool valve. So it will be smoother with less kick, and IMO, much better quality.

i agree, if at all possible pick up a PMR over the slg, there are a lot more mods out there for the pmr anyway

miller-the pmr is an unbalanced spool, and the matrix line is balanced spools right? what makes the difference?

In a balanced spool valve, you have 2 distinct areas of pressure. High pressure and low. By balancing where those pressures are, the high pressure air is ONLY used to fire the ball, the low pressure is used to cycle it. In the Matrix and Quest, this translates to them using a LPR to adjust the LP, however Droids and Luxe are LPR-less balanced valve spools.

In an unbalanced spool, there is no low pressure air, it's all high pressure.

so an unbalanced would not have a LPR right?(for the most part, im a little confused as to how you get a balanced spool without an lpr on the droid and luxe) thats got to be roufgher on the noid. also means a unbalanced will have more kick right?

Yes, unbalanced spools will generally have a rougher shot, and also get worse efficiency. Things like the Luxe and Droid use a fixed LP...it's still lower pressure, it's just not adjustable. As to how they actually achieve lowering the pressure, absolutely no clue. Never torn into either one enough to say how, and while the Droid's characteristics in it's shot and efficiency does imply balanced spool, the Luxe implies unbalanced. However, I've been reading that the Luxe IS a LPR-less balanced valve. One of these days I'll have to get hold of one and really learn them to see what differentiates them from being just a $1600 talking Shocker.

**Trbo323** · May 21st, 03:07 PM

hmm, ya cuz the shocker is a balanced spool right? so its a talking shocker without a lpr? i dont think anything makes it worth 1600, not even the tooless bolt removal

tlmiller · May 21st, 05:15 PM

Shockers don't have LPR's either. As far as toolless removal of everything, I could care less. But it must not be anywhere near that expensive, since the Victory will have that, as well as the internal plumbing, and will cost just a tad under $1200.

**Trbo323** · May 22nd, 02:29 PM

hmm, well they must have hired a really expensive voice then to put into the board, iv never heard one (nor do i care to) but it seems to be a shocker with different milling, a talking board, and....well i guess the internal plumbing is only on the upper model....and tooless bolt removal.

sp has their heads up their asses

That's basically been my take. A further evolution of the NXT as the NXT was an evolution of the SFT. It IS smoother than an NXT, it is more efficient than the NXT. But is it in another league? Not IMO. Unless I can tear one apart beside an NXT to really compare their bolt assemblies though, I can't say for sure they didn't change something major in the design.

Ok how can you tell what year a pmr is I had just bought one off ebay the guy listed it as a slg 08 I asked him what year and he said its 07-08 not sure so I went ahead and bought knowing that it was an pmr but not sure what year it is. Oh yeah I got for a steal the guy said it was his promo gun that stayed on the shelf and he used it once the gun looks brand new no scraches very clean all for $130 I was the 27th bid
