Penn National TG Sheets Question for TG

[Point_Given_Gal]

I really dont care for Penn National but my Dad wants to go to the OTB and he wanted me to get the TG Sheets (he is former Rags user - now prefers TG).  I was looking over the sheets and its a far cry from horses I am used to betting on at Belmont and Hollywood.  

Do the sheets work well at Penn National.  Is there a trick that I need to know to use them for this track?

Just asking just in case.  I have heard about the crap that has teken place there in the past and I just want to be cautious.
