Any Advice?

Do it, don't worry about it. It is an old wifes tail that comes from a combination of old rope seals (from the 50's and before) and early synthetics in the 70's not containing seal swellers.

Just to prempt the regular question that comes next, you can switch weight, brands, and from synth to mineral and back at will. It won't hurt anything.
