Thinking of spooling a couple of spinning reels with 30# test with 6# diameter. Any comments or recommendations?

IMHO its garbage. Get Sufix 832.

^ What he said.

As mentioned above I've only heard negative things about it. I'd go power pro or sufix 832.

Another vote for 832.

Just to help out - Fleet Farm currently has 832 on sale for $12.99 a spool - green and yellow, most line tests

Agree with the above and 30# would feel like rope to me on a spinning reel

Highest I use on spinning is 20#...and that's on a 3000

Thanks for all the response. I have decided to go with Suffix 832 20lb. test. Should have about a 6lb. diameter. Am I close?

this may be helpful - calculates spool capacity for different line diameters

This version works for stacking lines of different diameter

I think that's fine.
