Check all info.
If I remember seeing..mulch was more power than sand and even brush, so I agree with the 30%+ as I've remembered it in a blitz shot.
I would only use a wedge. I'm lucky w/ the punch a lot, with extra power and sometimes a full shot w/ the spin dot just on the mulch line, almost full BS.
But I'm still learning.
edit: I'd like to know the most popular courses for deep brush, mulch etc. because I'd like to get the Cleveland
115 yard wedge and use it on some courses where you may need it for long distance saves.
But I guess I will find out soon enough which are the common games w/ mulch etc.
