Ive used powerpro 10# in a number of spincasters(Omega, Goldcast, brown 33) and underspins. The biggest issue is the coating on new braid that will gum the pin and housing. I sprayed my line,pin,housing with reel magic and it solved that issue. So if going with the 33 use it a while with the braid to get it worn in some.
