Right now I'm mostly using the spyder sonix. Mostly. I put an Armson stealth barrell on it, an expansion chamber, new springs, drop forward, and I polished the bolt.
They are thicker than the stock hoses, which means they should be sturdier than the stock hoses. The only reason I bought these is because my stock hoses snaped.
Way too expensive. I was suprised that a couple inches of hoseing could retail for so much. I was expecting to only have to pay $2 for some new hoses, and I ended up paying $9.99 at crappy old Bad Boyz Toys. I tried to get some off the internet, but shipping brings the price to the same as the store.
Only get them if your stock hoses break. They add nothing to performance and don't make your gun look better at all if you use the grip shroud, which covers up the front block.
