I'm going for whitetail and want to increase the poundage I'm shooting because I'm paranoid that the arrow wont penetrate well enough at the current 55. However, I'm comfortable at 55 but could probably struggle for 65 or so. My arrow flight just looks really weak and slow compared to some of the speed bows I've seen at the range. Yup you guessed it, I'm a newbie.

Now what I need to know is, can I change out cams that will make drawing 65 lbs easier than the cams I have now. They are half way between circular and oval. I've seen more oval ones almost egg shaped and wonder if those would make drawing bow at higher poundages easier.

TIA
