My FPS upgrades any good?

Ok so i just got a tightbore and new bucking and now i am looking for a little more kick. I was thinking i would go with laylax because i like their parts. Here is what i want:
Laylax sears
laylax 150 spring
laylax spring guide
laylax cylinder head.
Is this a good any good?

Being that LayLax is a sub company of Prometheus, you are getting some decent quality in their parts, even tho I have a problem with their springs ( they lose their Tensile strength relatively early ).

Since my experience with Springers is limited, maybe somebody with more information can really point you in the right direction.

It seems to be a decent parts list. The only things I would change would be to add a Teflon cylinder... http://www.airsoftgi.com/product_info.php?cPath=31_201&products_id=3460
and also a Laylax zero trigger... http://www.airsoftgi.com/product_info.php?cPath=31_201&products_id=4113

the laylax head wont fit in the stock cylinder, if u buy the spring guide don't get the one that had the 7mm and 9mm guide that are interchangable just get a stright up 9mm, otherwise it will always unscrew in the cylinder (no fun)

Could you use Lock-Tight to fix the Problem ???

i don't have the money for the new cylinder and zero trigger. if i got the sears, a piston, and spring guide would i be able to run a 150?
