I assume you are referring to the RioGrande line with the welded loop. I use this on my 6wt for trout/steelhead and it is an excellent line. Very slick, durable and the loop is tough as nails. Has been through 2 seasons of abuse and looks like new.
It would work well for bass fishing because it is what I would call "oversized'. The 6 weight line is really more of a 6 1/2. One thing to be careful of is using it on rods with small guides/tip tops but with an 8wt this should not be a problem.
If you cast lots of bulky poppers, etc you may want consider a bass bug specialty line that you can shoot a mile but I prefer more versatility as I'm more of a trout guy.
Best of luck,
