Josh I use various sink tips on whatever line I'm using, one size does not fit all, but in this case most sizes will work on some. For instance when fishing Spey I can change from 85 grns all thge way upto 275 grns on a 10wt and still cast it as far as I need to. However on single handed rods I have to pretty much stick with whatever tip is actually the correct and specific weight for that particular rod.
I have made my own tips out of everything possible but now find it simple and easy to just purchase the ready made RIO tips at most fly shops. Theses tips come in various densitys and weights most have colored shrink wraps that may help you remember which is which.
Just an observation I have been fishing for steelhead for over 40 years and I am of the opinion that you can't catch fish everywhere that they will hold with the fly. Fish what you can cast and move on to water you can fish.
