calspeed vs lpp
calspeed is 304 stainless, lower grade
lpp 321 stainless, higher grade, welds on 321 are better/stronger on 321 compared to 304, so bonding two pieces of 321 will be of better quality
both will change color, fade, have water stains, etc
i personally have cal speed, cause i was ready to rock an roll, lpp didn't have them in stock for a long time...
