I've never had that issue. If a guy can stuff my straight wrestling takedowns, which most guys can't, I have judo and my standing submissions to fall back on. I can also pull guard on pretty much any 155 pounder I've ever stepped in the ring with.
If it comes to a throwdown, I really only have a few combinations, but I'm strong enough that I can drop someone with a big right hand or a knee. I prefer knees, but I do end up using my elbows and hands more, because they're faster.
