dudes, seriously using metal braided hose is like running an unglided wand, you just using the wrong stuff, parker paraflex is the only solution house ANYONE should ever use. I am still using the same stuff I bought from cobb like 7 year ago. when I ran goodyear I had to replace the stuff every year. with that said in 7 years time goodyear would have cost me 2100 to keep 200ft of it on my truck instead I have only paid $400. AND THE HOSE IS STILL ON MY REELS WORKING.
there are 3 other added bonuses besides the price, I get 7-8 more degrees at the wand, I don't burn grass and the stuff doesn't explode in the house and spew BLACK shit everywhere when the ends give out.
if you are using goodyear, your out of the loop
as for vac house, amflex is pretty much the best hose out there that I can find. bristor sells it and maybe some others just make sure its amflex. don't submerge it in sewer because for some reason its very hard to get the smell off the hose once you do.
