Almost no matter whose kettle you use, if it has a pickup tube in it, you'll struggle with too much whole hops in your boil.
They clog - and a real hassle. You are better off just bagging them. OR if you don't want to do that, you can buy a stainless steel coiled scrub pad (used for doing dishes) and stuff it around your pickup tube so that material/hop cones and leaves are first filtered by the stainless scrub pad. A trick one of our guys figured out on his kettles years back.
