Nope, they're great! I find the hop bags are really easy to use . I put the hops in, cinch the drawstring, then loop the drawstring around my mash paddle and lay it across the kettle. Keeps the bag suspended an it works great.
Take a look at DIY hop spiders too. If you haven't seen those, they're a pretty ingenious way to use a paint strainer/BIAB bag. Cheers!
