The problem with the few wiping calls, is not that the penalty is too low, but rather that refs think it is too high, and thus fear making the call.
Increasing the penalty would not mean more calls - actually the contrary.
I think 341 is fine, refs just need to grow a pair and make the call - and forget all about intent, which should not be relevant.
For instance, you get hit going into a bunker, slide, and the hit is gone... and you automatically incurr a 341..... rarely do refs make that call today, but they should, every time.
